Embodiment 1

[0017] Such as Figure 5-6 As shown, the embodiment of the present invention provides a permanent magnet transverse flux motor. The motor has a stator and a rotor. The rotor rotates with the rotor shaft 14. The rotor is connected end-to-end by a plurality of permanent magnets 13 to form a ring shape. The magnetizing direction of the magnet 13 is opposite; the stator is composed of a plurality of iron cores 11 and windings 12 respectively wound on the iron core 11, and the iron core 11 is arranged around the periphery of the rotor.

[0018] For the permanent magnet transverse flux motor with the above structure, the iron core 11 can be made of U-shaped silicon steel sheet, which is easy to process. The manufactured iron core 11 can be fixed on the motor casing, and the rotor adopts multiple permanent magnets connected end to end. The stator adopts a structure in which the winding 12 is directly wound on the iron core. Compared with the prior art, the rotor omits the rotor iron core...

Abstract

The invention discloses a permanent magnet transverse magnetic flow motor which is provided with a stator and a rotor. The rotor is in an annular shape formed by a plurality of permanent magnets in a head-to-tail connection mode. The magnetizing directions of two adjacent permanent magnets are opposite. The stator is composed of a plurality of iron cores and coils respectively wound on the iron cores. The iron cores are arranged around the periphery of the rotor. The permanent magnet transverse magnetic flow motor achieves simplification of the structure and the process, is easy to machine and manufacture and solves the technical problems that in the prior art, due to the complex structure, machining and manufacturing are difficult and heat dissipation is inconvenient.
