Outer rotor axial magnetic flux motor

Abstract

The invention relates to an outer rotor axial magnetic flux motor, which comprises two rotors, two groups of magnetic shoes, a stator, stator teeth and an air gap adjusting assembly, the two rotors are symmetrically installed on the inner side wall of the shell and are in sliding connection with the shell, and the inner side walls, away from the shell, of the two rotors are arranged in a splayed shape. The two groups of magnetic shoes are respectively attracted to the inner walls of the two rotors in a surrounding manner, and the sections of the two groups of magnetic shoes are distributed in a splayed shape; the stator is arranged inside the rotor and is fixedly connected with the front and rear side walls of the shell through a shaft lever; the stator teeth are integrally arranged on the outer side wall of the stator in an annular array and are wound with a winding; the cross section of the end surface of each stator tooth is in an isosceles trapezoid shape, and the two waist side surfaces of each stator tooth are respectively parallel to the inner side walls of the two groups of magnetic shoes; the air gap adjusting assembly drives the two rotors to be close to or away from each other, and the two rotors drive the two sets of magnetic shoes to be close to or away from the stator teeth so as to adjust the size of the air gap. According to the invention, the air gap can be adjusted without dismounting the stator and the rotor through forward and reverse rotation of the screw, and the operation is convenient.

Description

technical field [0001] The invention belongs to the field of motors, and in particular relates to an outer rotor axial flux motor. Background technique [0002] The working efficiency of the permanent magnet motor has been widely affirmed, and it can also carry a relatively large power density and effect in the actual working process. The working operation of the permanent magnet motor also has a compact structure, and the actual operation is also very reliable. At present, researchers are paying more and more attention to permanent magnet motors, and have begun to conduct in-depth research in order to apply permanent magnet motors to various high-tech fields. [0003] The permanent magnet motor can be divided into inner rotor and outer rotor. The structural characteristics of the outer rotor permanent magnet motor determine that the stator is located inside the rotor, and the heat converted from the loss generated in the stator can only be transferred to the base through t...

AI Technical Summary

Problems solved by technology

[0004] The axial permanent magnet motor is small in size and looks like a flat disc, so it is difficult to assemble, especially when it is necessary to adjust the uniformity of the air gap between the stator and the rotor, the stator and the rotor must be fastened first. The uniformity of the air gap between the stator and the rotor can be measured. If the air gap cannot meet the design requirements, the fastening bolts must be loosened, and the relative position between the stator and the rotor must be readjusted. After the relative position is adjusted, tighten the fastening bolts , measure the air gap between the stator and the rotor again, and so on, until the air gap between the stator and the rotor meets the design requirements, the stator and the rotor need to be assembled repeatedly during the whole adjustment process, the operation process is cumbersome and time-consuming, resulting in low processing efficiency
