A six-phase isolated permanent magnet motor

Abstract

The invention provides a six-phase isolated permanent magnet motor. The six-phase isolated permanent magnet motor comprises a shell, a permanent magnet, stator cores, a rotor core, armature windings and a shaft; 12 pairs of L-shaped stator cores are fixed in the shell; convex stator poles are at the inner side of the stator cores; the permanent magnet is clamped between the two stator cores, so that a pair of stator cores can be formed; two stator poles on a pair of stator cores are parallel; each stator pole is wound with the centralized armature windings; the armature windings of the two poles on the same pair of stator cores are opposite in winding direction and same in phase; the various armature windings in the circumference direction are divided into six phases according to different phases; 22 uniformly distributed convex poles are on the rotor core; and the 22 uniformly distributed convex poles and 24 stator poles form a 24 / 22-pole structure. The six-phase isolated permanent magnet motor provided by the invention has six-phase windings; after one phase is failed, various other phases can operate continuously; furthermore, the rotor is simple in structure; the rotor does not have a winding; and the mechanical strength is high.

Description

technical field [0001] The invention relates to a six-phase isolated permanent magnet motor, which belongs to the technical field of special motors. Background technique [0002] Electric energy has become an important material basis of modern human civilization. The motor is the basic equipment for producing and using electric energy and realizing electromechanical energy conversion. Most of the electrical energy currently used by humans is generated by generators. According to statistics, the world's industrial motors consume more than one-third of the total power generation. In my country, more than half of the annual power generation is consumed by electric motors and converted into mechanical power. Therefore, the progress of motor theory and technology plays an important role in the development of energy, efficient use of energy and energy conservation. [0003] With the development of society and economy, higher requirements are put forward for motors in the field...
