Abstract

The invention relates to the technical field of permanent magnet motors, and discloses a permanent magnet motor which comprises a motor casing, a rotor structure and a stator structure. The rotor structure comprises a magnetizer and permanent magnet groups. The stator structure comprises an inner stator and an outer stator, which are coaxially sleeved in sequence from inside to outside. A number of permanent magnet groups are arranged on the magnetizer in a circumferential array. The magnetizer is divided into an inner layer magnetic pole of the rotor and an outer layer magnetic pole of the rotor by the permanent magnet groups. The magnetizing directions of the adjacent permanent magnet groups are opposite. Each permanent magnet group comprises a left permanent magnet and a right permanentmagnet, and a gap is formed between the inner end of the left permanent magnet and the inner end of the right permanent magnet. The outer stator and the outer layer magnetic pole of the rotor form anouter air gap magnetic field of the motor. The inner stator and the inner layer magnetic pole of the rotor form an inner air gap magnetic field of the motor. Two air gap magnetic fields are provided,so that double air gaps formed by using the double-stator structure are realized, and the air gap of the motor is doubled.

Description

technical field [0001] The invention relates to the technical field of permanent magnet motors, in particular to a permanent magnet motor. Background technique [0002] The motor is an electromagnetic mechanical device that converts electrical energy into mechanical energy, and the power conversion and transmission of the motor occurs in the air gap between the stator and the rotor. Now all the motors in the world are composed of a stator and a rotor. This motor has only one air-gap field. When the motor is running, the magnetic field of the stator and the rotor of the motor is always fixed, and the air gap magnetic field of the motor can only be changed by changing the magnetic field of the other to make the motor work. This greatly limits the efficiency and power density of the motor. Contents of the invention [0003] The present invention mainly provides a permanent magnet motor, which solves the problem that the efficiency and power density of the motor are greatly ...
