Fig. 5 A and 5B are the operation principle schematic diagrames according to the motor of sub-controller in the electric machine of an embodiment of the present utility model and correspondence.
Direct current machine have response fast, bigger starting torque, possess the performance that nominal torque can be provided from zero rotating speed to rated speed, but the advantage of direct current machine is its shortcoming just also, because the performance of constant torque under the confidential generation nominal load of direct current, then armature field and rotor field must perseverance be kept 90 °, and this will be by carbon brush and commutator.Carbon brush and commutator can produce spark, carbon dust and therefore cause assembly damages except meeting when motor rotates, use occasion also is restricted.Alternating current machine does not have carbon brush and commutator, and is non-maintaining, firm, use extensively, but must just can reach with complicated control technology if will reach the performance that is equivalent to direct current machine on the characteristic.It is many that semiconductor develops rapid (PCC) power switching frequency quickening now, promotes the performance of drive motors.Microprocessor speed is also more and more faster, can realize AC Motor Control is placed the diaxon orthogonal coordinate system of a rotation, suitably controls alternating current machine at the diaxon current component, reaches similar DC MOTOR CONTROL and the performance suitable with direct current machine arranged.
Existing in addition a lot of microprocessor will be controlled motor, and essential function is made in the chip, and volume is more and more littler; The picture analog/digital converter (Analog-to-digital converter, ADC), pulse width modulation (pulse wide modulator, PWM) ... etc.Motor in the present embodiment is a dc brushless motor, promptly is to control the alternating current machine commutation in the electronics mode, and obtaining similar direct current machine characteristic does not have a kind of application of lacking in the direct current machine mechanism again.
The rotating speed of rotor is subjected to the speed and rotor number of poles (P) influence: the N=120.f/P of motor stator rotating magnetic field.Under rotor number of poles fixation case, the frequency that changes the stator rotating magnetic field just can change the rotating speed of rotor.
Sub-controller in the present embodiment promptly be used to control corresponding motor the stator rotating magnetic field frequency and the rotating speed of rotor feedback to control centre 502 proofreaies and correct repeatedly, in the hope of reaching mode near the direct current machine characteristic.That is to say that dc brushless motor can still can control rotor and keep certain rotating speed in the nominal load scope when load variations.
Sub-controller in the present embodiment comprises power supply unit and control part, and shown in Fig. 5 A: power supply unit provides three phase mains to motor, and control part is the supply frequency of conversion input on demand then.
Power supply unit can be directly with direct current input (being generally 24V) or with alternating current input (110V/220V), if input is that alternating current must change into direct current through transducer (converter) 504 earlier.No matter be that the input of direct current input or alternating current will change over to and must earlier direct voltage be changed into 3 phase voltages by converter (inverter) 506 before the motor coil and come drive motors.Converter (inverter) 506 is generally by 6 power transistors (Q1～Q6) be divided into upper arm (Q1, Q3, Q5)/underarm (Q2, Q4, Q6) connection motor as the switch of control flows through motor coil.Control part is then provided the opportunity of PWM (pulse width modulation) decision power transistor switch frequency and converter (inverter) 506 commutations by control centre 502.Dc brushless motor is generally wished in use, speed can be stable at set point and can not change too big speed control when load change the time, so motor internal is equipped with the Hall element (hall-sensor) 508 of energy induced field, as the loop circuit control of speed, the foundation of also controlling simultaneously as phase sequence.
Allow motor rotate, at first control part just must be according to the present position of the rotor that Hall element 508 is sensed, determine to open the order of power transistor among (or closing) converter (inverter) 506 then according to stator winding, shown in Fig. 5 B, AH in the converter (inverter), BH, CH (these are called the upper arm power transistor) and AL, BL, CL (these are called the underarm power transistor), make the electric current motor coil of flowing through in regular turn produce forward (or reverse) rotating magnetic field, and interact with the magnet of rotor, so just can make motor up time/inverse time rotation.When rotor turn to Hall element (hall-sensor) 506 induce another the group signal position the time, next group power transistor of opening again again in the converter 506 is modulated by the pwm pulse bandwidth by control centre 502, and so circulation motor just can be rotated further up to control centre's 502 decisions according to same direction and want rotor to stop then to close power transistor (or only opening the underarm power transistor); Oppositely then the power transistor opening sequence is opposite to want rotor.
Basically the method for opening of power transistor can be exemplified below, shown in Fig. 5 B:
One group of AH, one group → AH of BL, one group → BH of CL, one group → BH of CL, one group → CH of AL, one group → CH of AL, BL
But must not be split into AH, AL or BH, BL or CH, CL.In addition because electronic component always has the response time of switch, so power transistor will be taken into account the response time of part at the staggered time of Guan Yukai, otherwise when upper arm (or underarm) is not closed as yet fully, underarm (or upper arm) is just opened, and the result burns power transistor with regard to causing upper and lower arm short circuit.
When motor rotates, the speed that order (Command) and Hall element (hall-sensor) 508 signals that the speed that control centre 502 can be again sets according to sub-controller and adding/rate of deceleration is formed change compared (or by software computing) decide again by next group (AH, BL or AH, CL or BH, CL or ... ...) switch conduction, and ON time length.Speed is then opened length inadequately, and speed is excessive then to shorten, and this partially-working is just finished by pwm pulse bandwidth modulation system.
According to the technical solution of the utility model, can realize a kind of electric machine, have the following advantages: compare the driving of separate unit motor, electric machine efficient platform of the present utility model is wideer, more power saving; Can play the effect of shunting during many machine operation, remedy the sacrifice and the loss of motor efficient when big current work, guarantee the output of motor high efficiency, and through after the shunting, reduced of the impact of big electric current to the separate unit motor, the stability of motor and components and parts life-span strengthen greatly, the whole raising motor useful life; Because the shunting of many motors is handled, greatly reduce of the temperature rise influence of big current work to the separate unit motor, temperature rise is much smaller more than the separate unit machine operation when making the big current work of many motors; Shunt during because of many electric motor startings, avoided the impact of big electric current to the separate unit motor, the detent torque fluctuation is controlled, starts smooth-going.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
