Description

Power generation unit

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generating device, and more particularly to a first disk body having a plurality of magnets spaced apart in a circumferential direction and insulated between metal plates by a first disk body disposed between the two disk bodies The relative rotation between the second disks of the material causes the electromagnetic induction of the magnets and the metal frame to generate electricity. Background technique

In the current generator, it is converted into electric energy by a rotating motion transmitted to the rotating shaft of the power generator. The output of the power generator is connected to the system power or stored in the battery and used as power when needed.

There are several types of power generators, including, for example, a type using a turns, a type using a permanent magnet as a field magnet, or a structure of their type, a radial type in which the stator surrounds the outer portion of the cylindrical rotor And a shaft type in which the stator faces the dish rotor or the like in the axial direction. Each type has its own advantages and disadvantages, but if the efficiency required for power generation is significant, the permanent magnet type can be used as a field magnet because it can produce a comparison with a coil field magnet of the same physical size. A strong magnetic field increases the magnetic flux and increases the induced voltage.

Since electric energy is mainly dependent on the efficiency of the power generator, a more efficient power generator is required. Since the voltage generated is proportional to the number of magnetic poles of the field magnets. However, when the number of magnets of the coil or rotor is increased in order to increase the number of magnetic poles, the magnetic field of the field magnets may be reduced because each coil or magnet must be correspondingly reduced. Thus, a possible option is to maintain the magnetic field of the field magnets by increasing the number of coils or magnets of the same size, and amplifying the diameter of the rotor to increase the magnetic pole. This method is practical, however, amplifying the diameter of the rotor of the power generator will make the overall diameter of the power generator larger, which is undesirable because of the increased volume and increased cost.

Furthermore, in the case of the existing generator, the stator is mostly composed of a coil winding and a magnetic conductive material (such as a silicon steel sheet or a core), and thus has the disadvantages of heavy material weight, magnetic loss and eddy current loss, and thus Reducing the power generation efficiency will also cause the external volume to be too large, which is not conducive to the development of miniaturized motors. And market competition.

The structures of the generators currently seen are disclosed in the invention patents such as 1289969, 1290789, M374702 and publication number 200843293.

It is disclosed in the contents of the thin motor and generator dual-purpose machine described in the TW region M374702 patent, including: a casing; a two-plate type stator, which is relatively fixed in the casing, respectively comprises an insulating substrate, a copper-platinum layer On the side of the insulating substrate, the surface is provided with connected circuit coils, and each of the insulating substrates is respectively provided with a shaft hole; the rotating shaft is rotatably inserted into the casing and passes through the shaft holes of the two stators without a stator-shaped contact; and a disk-shaped rotor disposed between the two stators and having a disk body, wherein the plurality of magnets are arranged on opposite sides of the disk body in opposite magnetic poles, and the magnets correspond to copper and platinum Circuit coils on the layer. The disadvantage of this method is that the manufacturing process of the disc type stator is complicated, the assembly is difficult, and the assembly time is increased, thereby increasing the production cost, and the power generation efficiency of the generator is not high and does not conform to market competition.

In addition, the power generating device of the axially separated induction coil and the magnet described in the TW region 1289969 patent discloses that the magnet device includes a plurality of magnetic poles and is staggered in an N pole-S pole. a ring-shaped distribution; and an induction coil, which is mounted on the coil base, and the induction coil is wound around the wire loop type and leads to the two guide wires; wherein the induction coil and the magnet device are respectively mounted on the two opposite rotations On the object, the relative rotation of the two objects causes the induction coil to rotate relative to the magnet device, so that the induction coil generates an induced current. The disadvantage of this method is that: two members are used which can drive the induction coil to rotate relative to the magnet device, thereby increasing the use of the power source and increasing the cost due to the increase in the number of components, and also reducing the installation because the same axis is not used. And the accuracy of relative rotation.

Therefore, different design improvements are made based on the structure space type or the number of components, so as to be able to make a considerable difference with the existing structure or to improve the use efficiency or reduce the cost to increase the competitiveness, so there is a need for a power generation device. To solve the above problem.
