Title:
PERMANENT MAGNET BRUSHLESS MOTOR AND MANUFACTURING METHOD THEREFOR, MULTI-AXIS AIRCRAFT, AND ROBOT
Document Type and Number:
WIPO Patent Application WO/2023/020578
Kind Code:
A1
Abstract:
A permanent magnet brushless motor and a manufacturing method therefor, a multi-axis aircraft, and a robot. The permanent magnet brushless motor (100) is a fractional slot outer rotor motor, and the motor comprises a stator (1) and a rotor (2). The stator comprises a stator core (10) and a stator winding, and the stator winding is a non-staggered centralized winding having a span of 1. The rotor comprises a permanent magnet (21) and a rotor core (20). The stator core 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, and an insulating layer is provided on the surface of each stator tooth. The stator winding comprises a plurality of winding coils (11) formed by machine winding, and each of the plurality of winding coils is symmetrically arranged on the corresponding stator tooth by using a radial center axis (103) corresponding to the stator tooth as an axis of symmetry.
