Abstract: A less rare earth hybrid permanent magnet synchronous motor is proposed to address the issue of large usage of
the rare earth permanent magnet materials in surface permanent magnet synchronous motor for industrial robots. Through
modeling,simulation and optimization design, the performance of the motor was analyzed and compared. A prototype was
manufactured and a test platform was built to verify the superiority of the motor topology structure. This topology structure and
design method can provide certain reference and reference value for applications in similar situations.
