Abstract

The invention provides an axial structured permanent-magnet motor which is applicable for fields of a motor and a power generator. The axial structured permanent-magnet motor comprises two stators and a rotor, wherein the rotor is arranged between the two stators, and a gap exists between the stators and the rotor. In the axial structured permanent-magnet motor, the stators and the rotor are matched, the power density and the mechanical characteristic of the motor can be improved, and the fabrication cost of the motor is reduced; and the motor efficiency can be remarkably improved with the low loss characteristics of the stators made of amorphous and nanocrystalline material, the starting torque of the motor also can be increased with the high-permeability characteristics, and the output hardness of mechanical characteristic of the motor under a high rotational speed also can be improved with the wideband characteristics.

Description

technical field [0001] The invention belongs to the technical field of engines. Specifically, the invention relates to an axial structure permanent magnet motor, in particular to an axial structure permanent magnet generator or motor assembled with amorphous and nanocrystalline metal materials. Background technique [0002] Amorphous and nanocrystalline metal soft magnetic materials have excellent properties such as high magnetic permeability, low remanence, low loss, and broadband characteristics. They are used in high-frequency transformers, common-mode inductors, filters, and transformers. The development of high-frequency miniaturization and high efficiency has played a very good role in promoting. With the rise of new energy industries such as electric vehicles and wind power, more and more attention has been paid to high-efficiency amorphous and nanocrystalline permanent magnet motors; traditional amorphous and nanocrystalline permanent magnet motors are mostly radial ...
