Title:
FIVE-PHASE MOTORS FOR SERVO SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2022/199144
Kind Code:
A1
Abstract:
The present invention relates to the technical field of servo motors, and in particular to five-phase motors for servo systems. One five-phase motor for a servo system comprises: a motor rotating shaft; a rotor structure comprising a rotor iron core and twelve permanent magnets, twelve embedded holes which are arranged at equal intervals in the circumferential direction of the rotor iron core being formed in the rotor iron core; and a stator structure comprising a stator iron core and a stator winding, the stator iron core being provided with ten stator teeth which are sequentially arranged in the circumferential direction of the stator iron core. The other five-phase motor for a servo system comprises: a motor rotating shaft; a rotor structure comprising a rotor core and eight permanent magnets; and a stator structure comprising a stator iron core and a stator winding, the stator iron core being provided with ten stator teeth which are sequentially arranged in the circumferential direction of the stator iron core. The present invention can improve the torque density and the power density, and reduce the torque ripple.
