Abstract

The invention relates to a motor stator comprising a casing and a plurality of magnets arranged on the inner surface of the casing, wherein the magnets form at least a pair of magnetic poles each of which comprises multiple magnets, the outer surface of at least one of the multiple magnets is an approximate plane, the casing comprises a plurality of wall parts and a plurality of connection parts respectively connecting adjacent parts, and the inner surfaces of at least one pair of wall parts are planes approximately and used for installing the magnet the outer surface of which is an approximate plane. The motor stator provided by the invention utilizes multiple magnets with small sizes to form one magnetic pole, magnets are easy to manufacture and the use ratio of materials is high.

Description

technical field [0001] The invention relates to a motor stator. Background technique [0002] Japanese Patent Application Publication No. 10-201206 discloses a two-pole motor stator. The motor stator includes two strip-shaped arc-shaped magnets respectively installed on the inner surfaces of two opposite arc-shaped wall parts of the stator casing. [0003] However, in this kind of motor stator, the manufacturing process of the elongated arc-shaped magnet is complicated and the material utilization rate is low. [0004] The present invention aims to provide a motor stator that can improve the above problems. Contents of the invention [0005] On the one hand, the present invention provides a motor stator, which includes a casing and several magnets installed on the inner surface of the casing, the magnets form at least one pair of magnetic poles, each magnetic pole includes a plurality of magnets, at least one of the plurality of magnets The outer surface is substantiall...
