Abstract

The invention discloses an axial permanent magnet motor with a modularized amorphous alloy stator, comprising a stator and a rotor, wherein the rotor comprises a left rotor disk and a right rotor disk fixedly connected together with the left rotor disk; the stator comprises stator shafts and a stator disk arranged on the stator shafts; the left rotor disk and the right rotor disk are respectively arranged on the stator shafts arranged at two sides of the stator disk; the stator disk comprises M stator modules which are connected end to end to form a closed loop, wherein M is an integer which can be divided by 3 with no remainder; and each stator module comprises an insulating framework provided with a mounting hole in the middle, an amorphous alloy lamination arranged in the mounting hole and a coil wound on the outer surface of the insulating framework. The manufacture and the assembly of the axial permanent magnet motor can be simplified, and amorphous alloy can be conveniently applied to the manufacture of motor stators, therefore, the iron consumption of the motor is reduced, and the production efficiency, the operation efficiency and the power density of the motor are increased.

Description

technical field [0001] The invention relates to an axial permanent magnet motor, in particular to an axial permanent magnet motor adopting a modular amorphous alloy stator, and belongs to the technical field of motor design and manufacture. Background technique [0002] With the increasingly serious energy problems, new energy fields such as wind power generation and electric vehicles are developing rapidly. These fields require motors to have extremely high efficiency and power density. In order to meet these requirements, various new structures and new materials are continuously introduced into the design and manufacture of motors. [0003] Compared with traditional radial motors, axial permanent magnet motors have higher torque density, so they have attracted extensive attention from researchers at home and abroad. But axial motors have not been as widely used in industry as radial motors. This is mainly because the stator of the axial motor of the existing structure is...
