Embodiment
Embodiment one
Shown in Fig. 5-6, the embodiment of the invention provides a kind of permanent magnetism transverse flux motor, and this motor has stator and rotor, and rotor rotates with rotor shaft 14, rotor is connected by a plurality of permanent magnet 13 head and the tail and is circular, and the magnetizing direction of adjacent two permanent magnets 13 is opposite; Stator is made of a plurality of iron cores 11 and the winding 12 that is wrapped in respectively on the iron core 11, and a peripheral week of iron core 11 surrounding rotors arranges.
The permanent magnetism transverse flux motor of said structure, during making, iron core 11 can adopt the silicon steel sheet of U-shaped, be easy to processing, the iron core of making 11 can be fixed on the motor case, the cirque structure that rotor adopts a plurality of permanent magnets to be formed by connecting from beginning to end, stator adopts the structure of directly twining winding 12 at iron core, relative prior art, rotor has saved rotor core, has avoided installing at interval the operation of rotor core, stator has saved the permanent magnet that is embedded in wherein, avoided the complicated technology of embedded permanent magnet, overall structure is simple, is easy to processing.
In order to prevent the interelectrode leakageg between the permanent magnet, also the residual shim of making every the magnetic material can be set between adjacent two permanent magnets.
For the structure that makes motor is compacter, operational efficiency and generating efficiency are higher, and iron core 11 is specially U-shaped or C shape; The opening of iron core 11 is towards the center of circle of rotor; Rotor places in the opening of iron core 11.
Embodiment two
Shown in Fig. 7-10, on the basis of embodiment one, motor also have one be used for being connected with rotor shaft 14 and the circular rotor connector 15 and made by the non-magnetic material for the stator retainer ring 16 of fixedlying connected with motor case; The internal perisporium of rotor is fixedlyed connected with the periphery wall of this rotor connector 15; Iron core 11 all is fixed on the side of this stator retainer ring 16.Can adopt key to be connected between rotor connector 15 and the rotor shaft 14, be easy to install and be convenient to dismounting.
During making, the structure of iron core can adopt the silicon steel sheet of U-shaped, is easy to processing; As shown in Figure 9, can be at first the side of iron core 11 fixedly be distributed on the side of stator retainer ring 16, the winding that is wrapped on the iron core 11 can adopt concentrated winding (to be wrapped in separately on each iron core 11, to be easy to roll off the production line, as shown in Figure 7); Stator retainer ring 16 adopts stainless steel to make, and stator retainer ring 16 can add water cooling plant near the outside of winding, and is better to the cooling effect of winding.Iron core 11 all can be arranged in the two sides of stator retainer ring 16 in addition.
