Abstract

The invention discloses an axial magnetic field stator partitional flux switching memory motor. The memory motor comprises a first rotor (41), a second rotor (42), a stator (1) which is arranged between the first rotor (41) and the second rotor (42), and an installation shaft which is used for coaxially installing the stator (1), the first rotor (41) and the second rotor (42). The stator (1) comprises a stator iron core (2), a number of permanent magnets (3), a three-phase armature winding (5) and a single phase pulse winding (6). The stator iron core (2) comprises a first stator iron core (21) and a second stator iron core (22), wherein the first stator iron core (21) and the second stator iron core (22) have the same structure and are coaxially and oppositely arranged. The stator iron core (2) comprises a stator yoke (2.1) and a stator tooth (2.2). According to the invention, the power density of the motor is improved; the rotation speed operation range is wide; and a no-load air gap magnetic field is adjustable.

Description

technical field

[0001] The invention relates to an adjustable magnetic flux permanent magnet motor, in particular to an axial magnetic field stator segmented magnetic flux switching memory motor. Background technique

[0002] In the field of motors, due to the inherent characteristics of ordinary permanent magnet materials (such as NdFeB), the air gap magnetic field in the motor is basically kept constant, and the speed regulation range is very limited when operating as an electric motor. The application of wide-speed adjustable direct drive applications such as electric vehicles and aerospace is limited to a certain extent. Therefore, the adjustable flux permanent magnet motor aimed at realizing the effective adjustment of the air gap magnetic field of the permanent magnet motor has always been a hot spot and difficulty in the field of motor research. . Permanent magnet memory motor (hereinafter referred to as "memory motor") is a new type of flux controllable permanent ma...
