Title:
PERMANENT MAGNET BRUSHLESS MOTOR AND MANUFACTURING METHOD THEREFOR, JOINT ACTUATOR, AND ROBOT
Document Type and Number:
WIPO Patent Application WO/2023/020601
Kind Code:
A1
Abstract:
A permanent magnet brushless motor (100) and a manufacturing method therefor. The permanent magnet brushless motor (100) is a fractional slot inner rotor motor, and the permanent magnet brushless motor (100) comprises a stator (1) and a rotor (2). The stator (1) comprises a stator core (10) and a stator winding of a non-staggered centralized winding having a span of 1; the rotor (2) comprises a permanent magnet carrier (20) and a permanent magnet (21) provided on the outer side of the permanent magnet carrier (20); the stator core (10) comprises a stator yoke portion (101) and a stator tooth portion; the stator tooth portion comprises a plurality of stator teeth (102) provided on the stator yoke portion (101); an insulating layer is provided on the surface of each stator tooth (102); the stator winding comprises a plurality of winding coils (11) formed by machine winding; and each of the plurality of winding coils (11) is symmetrically arranged on the corresponding stator tooth (102) by using a radial central axis (103) corresponding to the stator tooth (102) as an axis of symmetry.
