Magnetic steel interleaved multistage axial magnetic flux permanent magnet kinetic energy apparatus

Abstract

The invention relates to an interleaved magnetic steel rotor set. The interleaved magnetic steel rotor set comprises at least three rotors formed by backboards and magnetic steel, the rotors comprise a starting-end rotor and a bottom-end rotor, one sides of the backboards of the starting-end rotor and the bottom-end rotor are provided with the magnetic steel, at least an intermediate rotor is arranged between the starting-end rotor and the bottom-end rotor, two sides of the backboard of the intermediate rotor are respectively provided with the magnetic steel, a certain angle is reserved between the magnetization direction of magnets of the magnetic steel at two sides of the backboard of the intermediate rotor and the axial direction, and magnetic poles of the magnetic steel are arranged on the backboard in an alternative manner and are automatically aligned with corresponding magnetic poles of the magnetic steel of the adjacent rotors during assembling. The beneficial effects of the interleaved magnetic steel rotor set are that the complexity of a superposed axial motor structure and the production process is greatly reduced, the production efficiency is improved, the motor cost is greatly reduced, and the problem of low axial motor power in the condition of limited radial dimension is solved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, and in particular to a magnetic steel interlaced multistage axial magnetic flux permanent magnet kinetic energy device. Background technique [0002] There are two types of traditional multi-stage superimposed axial motors. One is to install multiple single axial motors on the same shaft, that is, whether it is a permanent magnet or a magnetic backplane, it is an integer multiple of the amount of a single motor. The stacking scheme of this method has poor economy, high cost, and long axial length. At the same time, the electrical connection between the windings is very difficult, the consistency of the windings is difficult to guarantee, and it is not mass-producible; the other such as the patent CN 203660839 U "Modular multi-layer disc motor based on effective magnetic domain technology" describes a disc rotor with multiple permanent magnets fixed on a disc surface and a disc stator...

AI Technical Summary

Problems solved by technology

[0003] In view of the above-mentioned defects of the prior art, the present invention solves the problem that the structure and production process of the existing superimposed axial motor are complicated, the economy is poor, the production cost is extremely high or it does not have mass production, and the radial size is limited. In this situation, the power of the axial motor cannot be increased, etc.
