Description

The present invention relates to a motor device, and more particularly to a motor device whose rotation speed can be switched.

A conventional motor device (not shown) has a rotor unit, a stator unit, three coil units wound around the stator unit, and a control unit.
The control unit controls the power supply of each coil unit, whereby the rotor unit rotates with respect to the stator unit to provide power.

Under general circumstances, a motor device used by an automobile, an air conditioner, a compressor, or the like has a load amount at startup larger than a load amount at operation.
Therefore, for smooth start-up, general motor devices are designed to have relatively high output power and rotation speed.
However, even after the motor device starts operation, it provides the same output power and rotation speed and continues to operate, which not only causes energy waste but also does not match the trend of the times when energy saving is required.

In order to solve the above problem, some motor devices are currently equipped with a converter transformer circuit, and the magnitude of the output voltage of the AC power supply of each coil unit or the output current frequency is adjusted to adjust the output current frequency of the motor device. The output power and rotation speed are changed.
However, since the converter transformer circuit structure is complicated, the design and manufacturing costs are high.

The prior art has the drawback of high design and manufacturing costs due to the complexity of the converter transformer circuit structure.

The present invention relates to a motor device in which the rotation speed can be easily changed and the manufacturing cost is not high.

The motor device according to the present invention includes a rotor unit, a stator unit, at least one coil unit, and a changeover switch unit.
The stator unit rotates the rotor unit relative to each other.
The at least one coil unit has a first coil and a second coil that wind around the stator unit, and the number of winding magnetic poles of the first coil is smaller than the number of winding magnetic poles of the second coil.
The changeover switch unit is electrically connected to the first coil and the second coil, and is controlled to individually switch whether the first coil and the second coil receive electrical energy or not. For,

The effects of the present invention are as follows.
Since the first coil and the second coil with different numbers of winding magnetic poles are installed and the changeover switch unit is installed in combination, the changeover switch unit is controlled based on different usage needs, and the use of the first coil or the second coil is used. Since switching can be selected and the rotation speed is switched to a different rotation speed, the effect of the rotation speed adjustment can be achieved in a situation where the cost can be controlled.

(One Embodiment)
As shown in FIGS. 1 and 2, the first embodiment of the motor device according to the present invention is applied to the electrical connection to the three-phase power supply 9, and the rotor unit 2, the stator unit 3, and the three coil units 4 are applied. , The changeover switch unit 5 and the control unit 6.

The rotor unit 2 rotates around its own axis.

The stator unit 3 is installed around the rotor unit 2, and the rotor unit 2 is rotated relative to each other to have a plurality of first lead wire tanks 31.
In the present embodiment, the number of each first wire tank 31 is 36, but the stator unit 3 has a different number of first wire tanks 31 as actually required, and is not limited thereto.

Each coil unit 4 has a first coil 41 and a second coil 42 that are wound around each first lead wire tank 31.
The number of wound magnetic poles of the first coil 41 is smaller than the number of wound magnetic poles of the second coil 42.
The output power of the first coil 41 is larger than the output power of the second coil 42.
The wire diameter of the first coil 41 is larger than the wire diameter of the second coil 42.
The winding pole distance of the first coil 41 is larger than the winding pole distance of the second coil 42.
The output power of the first coil 41 is preferably the display power of the motor device.

As shown in FIGS. 1, 3 and 4, each coil unit 4 exhibits a star-shaped (or Y-shaped) tangent as shown in FIG. 3, or a triangular (Δ) tangent as shown in FIG. It is electrically connected to each of the three-phase power supplies 9.

Each coil unit 4 is a three-phase coil, and the winding installation method corresponding to each other between the three-phase coils is well known in this region and will not be described in detail.
Moreover, the number of winding coils shown in FIGS. 2, 8, 11, 13, 15, 18, and 21 of the present invention is merely an example for explaining the winding method, and represents a specific number of winding coils. is not.

Each first coil 41 and each second coil 42 preferably uses a distributed windings scheme to perform windings (third coil 43 below (see FIG. 11)).
Therefore, the number of coils wound by the coil is uniformly distributed in a large number of corresponding first wire tanks 31.
However, for the sake of clarity, in FIGS. 6, 7 and 9, each of the first coil 41 and each second coil 421 will be illustrated and described with only one coil thereof.

As shown in FIGS. 1 and 2, the changeover switch unit 5 is electrically connected to the power supply 9, the control unit 6, each first coil 41, and each second coil 42.

The control unit 6 controls the changeover switch unit 5, selects and switches each first coil 41 or each second coil 42, and electrically connects to the power supply 9.
The control unit 6 controls the changeover switch unit 5 when the motor device is started or needs the first output, switches and selects each first coil 41, and electrically connects to the power supply 9.
After startup or when the second output is needed, the changeover switch unit 5 is controlled, each second coil 42 is switched and selected, and electrically connected to the power supply 9.
The first output need is a relatively high power output and a relatively high rotation speed is required, and the second output need is a relatively low power output and a relatively low rotation speed is required.

As shown in FIGS. 1, 2 and 5, the principle is explained as follows.
The output power unit of a normal motor device is horsepower (abbreviated as horsepower, hp), which is the product of torque and rotational speed.

The formula of torque is as follows. T is torque, B is magnetic field, I is current, L is coil length, D is coil width, N is number of coils, and θ is the angle between magnetic field B and current I.
The current I is directly proportional to the power of the wire diameter and is related to the number of coils N.

<Number 1>

Formula 1 derives how in the same motor unit:
<Number 2>

The formula of the synchronous rotation speed of the motor device is as follows, _ns is the synchronous rotation speed, f is the frequency of the power supply 9, and P is the number of poles.
In Taiwan, the frequency f of the power supply 9 is generally 60 Hz.

<Number 3>

The winding pole distance formula is:
<Number 4>
Winding pole distance = number of tanks / number of magnetic poles

As shown in FIGS. 2, 6 and 7, in the present embodiment, the number of tanks of the first lead wire tank 31 of the stator unit 3 is 36, and each first coil 41 and each second coil 42 are wound around. The number of magnetic poles is set to 4 poles and 12 poles, respectively.
Therefore, based on formulas 3 and 4, the winding pole distances of the first coil 41 and the second coil 42 are 9 and 3, respectively, as shown in FIGS. 6 and 7, respectively.
The rotation speed is 1800 rotations per minute (Revolution (s) Per Minute, abbreviated as rpm) and 600 rotations, and preferably, the tooth pitch between each first coil 41 and each second coil 42 is different. Designed to 1, but not limited to this.

The number of the first lead wire tank 31, the number of magnetic poles around which the first coil 41 and the second coil 42 are wound are both set according to actual needs, and are not limited thereto.
For example, as shown in FIGS. 8 and 9, the stator unit 3 has 24 first lead wire tanks 31, and the number of magnetic poles around which each first coil 41 and each second coil 42 are wound is 4 poles, respectively. , 8 poles.
Thus, based on formulas 3 and 4, the winding pole distances of the first coil 41 and each second coil 42 are 6 and 3, respectively, and the rotation speeds are 1800 rpm and 900 rpm.
Preferably, the tooth pitch between the first coils 41 is designed to be 2, and the tooth pitch between the second coils 42 is designed to be 1, but the present invention is not limited to this.

As shown in FIGS. 1 and 2, in the present embodiment, the output powers of the first coil 41 and the second coil 42 are designed to be 2 horsepower and 1/4 horsepower, respectively.
The number of windings of each of the first coil 41 and each of the second coil 42 is not described in detail here because a person having ordinary knowledge in this area can adjust the formula 1 and the actual needs by himself / herself.

In actual use, when the motor device is activated, the control unit 6 controls the changeover switch unit 5, switches and selects each first coil 41 (preferably display power), and supplies electricity to the three-phase input of the power supply 9, respectively. Connect with each other.
At this time, the number of poles of each first coil 41 is 4 and the output power is 2 horsepower. Therefore, at this time, the rotation speed of the motor device is 1800 rpm and the output power is 2 horsepower. ..
After the motor device is started and the set load is reached, the control unit 6 controls the changeover switch unit 5, switches and selects each second coil 42, and electrically connects to the three-phase input of the power supply 9.
At this time, the number of poles of each second coil 42 is 12 and the output power is 1/4 horsepower. Therefore, at this time, the rotation speed of the motor device is 600 rotations per minute, and the output power is 1/4. It is horsepower.

When the load changes during the operation of the motor unit and higher output power and relatively higher rotational speed are required (ie, first output needs), the control unit 6 further controls the changeover switch unit 5 and each first coil. 41 is switched and selected, and each is electrically connected to the three-phase input of the power supply 9.
When the load changes and a relatively small output power and a relatively low rotation speed are required (ie, second output needs), the control unit 6 controls the changeover switch unit 5 and switches to each second coil 42 to select. Each is electrically connected to the three-phase input of the power supply 9.

The first output needs and the second output needs can be designed according to the settings such as temperature and pressure.
For example, when applying a motor device to an air conditioner, the first output need is set for a relatively large temperature difference setting and the second output need is set for a relatively low temperature difference setting. ..
When the air conditioner starts operation, the temperature difference between the room temperature and the set temperature is relatively large at this time, so the operation is performed by switching to each first coil 41.
After the air conditioner operates for a certain period of time and the temperature difference between the room temperature and the set temperature becomes equal to or less than a certain value, the second coil 42 is switched to the operation.
In this way, switching output can be performed correspondingly according to different usage needs.

Summarizing the above explanations, the advantages of this embodiment can be summarized as follows.
1. 1. The first coil 41 and the second coil 42 having different numbers of winding magnetic poles are installed, and the changeover switch unit 5 is installed and controlled in combination, and the first coil 41 and the second coil 42 receive or receive electric energy. In order to switch individually, the first coil 41 or the second coil 42 is switched and selected and used based on different usage needs, and the rotation speed is switched to a different one. Thus, the converter transformer circuit is switched in a situation where it is not necessary to add it. The switch unit 5 can be easily switched and adjusted according to various rotation speed needs. Compared with the conventional technique, this embodiment achieves the effect of rotation speed adjustment in a situation where the cost can be controlled. it can.

2. Since the powers of the first coil 41 and the second coil 42 can be designed differently and switched to the required power based on different usage needs, the cost can be controlled, and the effect of energy saving is extremely high. Further, when the operation of the motor device reaches the set load, it is switched to each second coil 42 having a relatively low power and rotation speed, and the wear generated during the high-speed operation of the motor device is reduced, so that the maintenance cost is reduced. Have an effect.

3. 3. Since each second coil 42 having a relatively small wire diameter is installed relatively close to the rotor unit 2, the distance between each second coil 42 having a relatively small current and the rotor unit 2 can be shortened, which is further excellent. A magnetic conduction effect can be obtained.

10 and 11 are the second embodiments of the motor device according to the present invention.
The second embodiment is similar to the first embodiment.
The differences between the second embodiment and the first embodiment are as follows.

The stator unit 3 has 24 first wire tanks 31.

Each coil unit 4 further includes a third coil 43 that winds around each first wire tank 31.
The number of wound magnetic poles of the third coil 43 is larger than the number of wound magnetic poles of the second coil 42, and the output power of the third coil 43 is smaller than the output power of the second coil 42.
The wire diameter of the third coil 43 is smaller than the wire diameter of the second coil 42, and the winding pole distance of the third coil 43 is smaller than the winding pole distance of the second coil 42.

In each coil unit 4, the winding and installing positions are the third coil 43, the second coil 42, and the first coil 41 in order from the rotor unit 2 from the near side to the far side.

In the present embodiment, the number of tanks of the first wire tank 31 of the stator unit 3 is 24, and the number of magnetic poles around which each of the first coil 41, each second coil 42, and each third coil 43 is wound is four poles. , 8 poles, 12 poles.
Therefore, based on formulas 3 and 4, the winding pole distances of each of the first coil 41, each second coil 42, and each third coil 43 are 6, 3, and 2, respectively, and the corresponding rotation speeds are 1800 per minute. , 900, 600 rotations.

In the present embodiment, the output powers of the first coil 41, the second coil 42, and the third coil 43 are designed to be 2 horsepower, 1/2 horsepower, and 1/4 horsepower, respectively.
The number of windings of each first coil 41, each second coil 42, and each third coil 43 can be adjusted by a person having ordinary knowledge in this area according to the formula 1 and the actual need. I will not mention it.

In actual use, the control unit 6 starts the motor device, or controls the changeover switch unit 5 when the first output needs are needed, switches and selects each first coil 41, and three-phases of the power supply 9, respectively. It is electrically connected to the input.
When the motor device has a second output need, the changeover switch unit 5 is controlled, each second coil 42 is switched and selected, and each is electrically connected to the three-phase input of the power supply 9.
When there is a need for a third output, the changeover switch unit 5 is controlled, each third coil 43 is switched and selected, and each is electrically connected to the three-phase input of the power supply 9.
The power output of the third output need is lower than that of the second output need, and the rotation speed need is also lower.

In actual use, when the motor device is started, the control unit 6 controls the changeover switch unit 5, switches and selects each first coil 41, and electrically connects to the three-phase input of the power supply 9.
After the motor device is started and the set load is reached, the control unit 6 controls the changeover switch unit 5, switches and selects each second coil 42, and electrically connects to the three-phase input of the power supply 9.

During operation of the motor unit, when the load changes and higher output power and relatively high rotational speed are required (ie, first output needs), the control unit 6 further controls the changeover switch unit 5 and each first coil. 41 is switched and selected, and each is electrically connected to the three-phase input of the power supply 9.
When the load changes and a relatively small output power and a relatively low rotation speed are required (that is, a second output need or a third output need), the control unit 6 controls the changeover switch unit 5 based on the needs. The second coil 42 is switched and selected, or each third coil 43 is electrically connected to the three-phase input of the power supply 9.

In this way, the second embodiment can achieve the same purpose and effect as the first embodiment, and by adding each third coil 43, the third output need can be provided, and the user can switch and select. It has better application elasticity.

12 and 13 are the third embodiment of the motor device according to the present invention.
The third embodiment is similar to the first embodiment.
The differences between the third embodiment and the first embodiment are as follows.

The motor device is a single-phase motor and also has a coil unit 4.
The coil unit 4 further has an auxiliary coil 44 (Auxiliary Winding) or a start winding (Start Winding) that winds around each first lead wire tank 31 and assists the start-up.
The first coil 41 and the second coil 42 are used as a main coil (main winding).
The auxiliary coil 44 preferably achieves a more excellent start-up control effect with a difference of 90 degrees between the installation phase in space and the corresponding first coil 41.
The method of installing the auxiliary coil on the single-phase motor is well known in the industry and will not be described in detail here.

In actual use, when the motor device is activated, the control unit 6 controls the changeover switch unit 5, switches and selects the first coil 41 and the auxiliary coil 44, and electrically connects to the single-phase power supply 9.
When the motor device is started and reaches a certain degree (preferably, the rotation speed is around 75% of the synchronous rotation speed), the control unit 6 controls the changeover switch unit 5, and only the first coil 41 is switched and selected. It is electrically connected to the power supply 9, and at this time, the auxiliary coil 44 is already cut off.
Subsequently, after the motor device is started and reaches the set load, the control unit 6 controls the changeover switch unit 5, switches and selects the second coil 42, electrically connects to the power supply 9, and connects the motor device to the power source 9. It reduces the output power and the rotation speed.

When the load changes during the operation of the motor unit and higher output power and relatively higher rotational speed are required (ie, first output needs), the control unit 6 further controls the changeover switch unit 5 and the first coil 41. The switching selection is returned to, and the power supply 9 is electrically connected.
When the load changes and a relatively small output power and a relatively low rotation speed are required (ie, second output needs), the control unit 6 controls the changeover switch unit 5 and returns the changeover selection to the second coil 42 again. It is electrically connected to the power supply 9.

In this way, the third embodiment can achieve the same purpose and effect as the first embodiment, and is well applied to a single-phase motor device.

14, 15 and 16 are the fourth embodiments of the motor device according to the present invention.
The fourth embodiment is similar to the first embodiment.
The differences between the fourth embodiment and the first embodiment are as follows.

The motor device is further applied to the electrical connection to the battery module 8.

The stator unit 3 further includes a plurality of second wire tanks 32.
The depth of each first wire tank 31 is larger than the depth of each second wire tank 32, and each first wire tank 31 and each second wire tank 32 are installed so as to intersect and surround each other, preferably both. It is installed at uniform intervals, but is not limited to this.

In the present embodiment, the number of tanks of each first wire tank 31 is 18, and the number of tanks of each second wire tank 32 is 18, and the total number is 36. However, the stator unit 3 is actually used. If necessary, it has a different number of each first wire tank 31 and each second wire tank 32, but is not limited to this.

Each first coil 41 winds around each first lead wire tank 31.
Each second coil 42 winds around each second lead wire tank 32.
The output power of each first coil 41 is larger than the output power of each second coil 42, the number of wound magnetic poles of each first coil 41 is smaller than the number of wound magnetic poles of each second coil 42, and each first coil 41 The wire diameter of is larger than the wire diameter of each second coil 42.

The depth of each first wire tank 31 and each second wire tank 32 is directly proportional to the wire diameter size and power size of the first coil 41 and the second coil 42 installed correspondingly, and the power size is large. It is related to the number of winding magnetic poles.
The number of windings of the first coil 41 and the second coil 42 will not be described in detail here because a person having ordinary knowledge in this area can adjust the formula 1 and the actual needs by himself / herself.

Both the first coil 41 and the second coil 42 are wound using a distributed winding method (the third coil 43 described below, see FIG. 17), and so is the fourth coil 45 (see FIG. 20).
Therefore, the number of coils wound by the coil is distributed in the corresponding first wire tank 31 and the second wire tank 32 (the third coil 43 and the fourth coil 45 described below are the third wire tank 33 and the fourth, respectively. Corresponds to the wire tank 34).
However, in order to clarify the illustration, only the one-phase coil unit 4 is shown in FIGS. 16, 19, and 22, and one coil is used for the first coil 41, the second coil 42, and the third coil, respectively. Coil 43. And the fourth coil 45 will be described.

As shown in FIGS. 14, 15 and 16, the changeover switch unit 5 is electrically connected to and controlled by each of the first coil 41, each second coil 42, the control unit 6, the power supply 9 and the battery module 8. Each of the first coil 41 and each second coil 42 individually switches whether to receive or not receive electric energy, and under control, each of the first coil 41 and each second coil 42 receives electric energy by the power supply 9. Is individually switched between receiving the coil and providing electrical energy to the battery module 8.

In the present embodiment, the number of tanks of each first wire tank 31 of the stator unit 3 is 18, and the number of tanks of each second wire tank 32 is 18, a total of 36, and each first coil 41. The number of magnetic poles around which each second coil 42 is wound is designed to be 2 poles and 6 poles, respectively.
Based on the above formulas 3 and 4, the winding pole distances of each of the first coil 41 and each of the second coils 42 are 9 and 3, respectively, and if calculated by the total number, 18 and 6 shown in FIG. The rotation speeds of the coil 41 and each of the second coils 42 are 3600 rotations and 1200 rotations per minute, respectively.
In FIG. 16, the tooth pitch (tooth pitch) between the corresponding first coil 41 and the corresponding second coil 42 is described as 1, but is not limited thereto.

During actual operation, the control unit 6 controls the changeover switch unit 5 and operates in the motor mode or the generator mode.

In the motor mode, as described above, the torque and power required at startup are relatively large.
Therefore, when the control unit 6 is started, the changeover switch unit 5 is controlled and used by switching to the first coil 41 having a relatively large power, and is switched to the second coil 42 having a relatively small power during the maintenance operation after the start. use.
In the operation process, when the load changes and the output power needs to be increased or decreased, or the rotation speed is changed, the first coil 41 or the second coil 42 is switched and used according to the needs.

When the motor device has extra energy and can be reclaimed, for example, when it is applied to an electric vehicle and it is necessary to step on the brake to decelerate, the control unit 6 controls the changeover switch unit 5 to switch to the generator mode. ..
At this time, the control unit 6 controls the changeover switch unit 5, switches to the first coil 41 or the second coil 42, which is not used at that time, and electrically connects to the battery module 8.
For example, at this time, the first coil 41 is electrically connected to the power supply 9, is used for driving, is switched to the second coil 42, is selected, and is electrically connected to the battery module 8.
As a result, the second coil 42 generates sensitive power by operating the motor device and stores electricity in the battery module 8.
In this way, the excess energy of the motor device is reclaimed and used to increase the energy utilization rate.

In this way, the fourth embodiment can achieve the same purpose and effect as the first embodiment, and has the following effects.

1. 1. A first coil 41 and a second coil 42 are installed, and the changeover switch unit 5 is simultaneously driven and driven in order to individually switch whether the first coil 41 and the second coil 42 receive or provide electric energy. It can provide a power generation function and increase the energy utilization rate. Since each first lead wire tank 31 and each second lead wire tank 32 are installed and the first coil 41 and the second coil 42 are installed respectively, the magnetic field lines of the first coil 41 and the second coil 42 are distributed in a staggered manner. , The independence of the magnetic fields generated by both can be enhanced, the mutual influence of the magnetic forces of both can be reduced, and further excellent drive operation effect and power generation effect can be achieved. Moreover, since the technology of the stator unit 3 currently manufactured is manufactured by stacking several press-formed silicon steel plates, the manufacturing difference between the present embodiment and the existing stator unit 3 is different. Only using the mold, there is no difference in the manufacturing process and assembly. That is, since the stator unit 3 of the present embodiment hardly increases the manufacturing cost, the motor device of the present embodiment simultaneously provides the drive and power generation functions, can increase the energy utilization rate, and suppress the production and maintenance costs. You can also.

2. Each first wire tank 31 and each second wire tank 32 are designed to be installed so as to intersect and surround each other, and the first coil 41 having a relatively large output power is installed in each relatively deep first wire tank 31. Since the second coil 42, which is installed and has a relatively small output power, is installed in each of the relatively shallow second wire tanks 32, the first coil 41 and the second coil 42 are not only as close to the rotor unit 2 as possible. It is also possible to obtain an even better electromagnetic sensitivity effect. Moreover, when the first coil 41 and the second coil 42 are wound in the same wire tank, it is possible to avoid the occurrence of a situation in which the distances between the same coil unit and the rotor unit 2 do not match in each wire tank. Taking the second coil 42 as an example, the distance when the second coil 42 and the first coil 41 are wound together in the same wire tank, and the distance when the second coil 42 is wound independently in one wire tank. In terms of distance, there is a difference between the two. In this way, the electromagnetic sensitive effect is different from the expected effect, and in the present embodiment, in each of the first wire tank 31 and each second wire tank 32 in which the depth of the first coil 41 and the second coil 42 and their power are in direct proportion to each other. This situation can be avoided, and it has an even better electromagnetic sensitivity effect.

17, 18 and 19 are the fifth embodiment of the motor device according to the present invention.
The fifth embodiment is similar to the fourth embodiment, but the differences between the fifth embodiment and the fourth embodiment are as follows.

The motor device further comprises a third coil 43.
The stator unit 3 further includes a plurality of third wire tanks 33 around which the third coil 43 is wound.
The depth of each third wire tank 33 is shallower than that of each second wire tank 32.
Each first wire tank 31, each second wire tank 32, and each third wire tank 33 are installed so as to intersect each other.
In the present embodiment, the number of tanks of each first wire tank 31, each second wire tank 32, and each third wire tank 33 is 12, and therefore, each first wire tank 31, each second wire tank 31, is preferable.
