Title:
BRUSHLESS MOTOR AND ROTOR THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/087668
Kind Code:
A1
Abstract:
A brushless motor and a rotor thereof. The rotor of the brushless motor comprises a rotor core (10), multiple first magnetic steels (20) that generate a first magnetic field in the radial direction of the rotor core (10), and multiple second magnetic steels (30) that generate a second magnetic field in the tangential direction of the rotor core (10); and the multiple first magnetic steels (20) and the multiple second magnetic steels (30) are alternately arranged one by one in the circumferential direction of the rotor core (10), such that the first magnetic field and the second magnetic field are mixed to form a mixed magnetic field. The rotor can improve electromagnetic noise of the motor and provide counter electromotive force having better sine degree, and can satisfy requirements of FOC driving, reduce the cost of the motor, improve the performance of the motor, and reduce the weight of the motor.
