Title:
STATOR CORE AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2020/258758
Kind Code:
A1
Abstract:
The present application discloses a stator core and a motor, wherein the stator core comprises a stator yoke and a plurality of stator teeth, the plurality of stator teeth are arranged at intervals along a circumferential direction of the stator yoke, and the plurality of stator teeth are located on one side of the stator yoke in an axial direction, the plurality of stator teeth are divided into a plurality of stator teeth pairs, the minimum spacing between the two stator teeth in each stator teeth pair is A, the minimum spacing between two adjacent stator teeth pairs is B, and A≤B. In the present application, due to A≤B, the cogging torque of the motor can be reduced, the magnetic flux leakage between the teeth and between the teeth pairs can be reduced, and the performance of the motor is improved.
