Abstract: To enhance the electromagnetic torque of the motor and reduce the usage of rare-earth permanent magnets, a multi-layer flux-barrier combined-pole biased permanent-magnet synchronous machine (MLFB-CPB-PMSM) was proposed, the motor enhances its electromagnetic performance by offsetting the permanent magnetic field through an asymmetric combined-pole structure. Firstly, the no-load and on-load electromagnetic performance of MLFB-CPB-PMSM under different structural parameters was analyzed. Secondly, under the condition of the same amount of NdFeB, the performance of MLFB-CPB-PMSM was compared with that of the symmetrical permanent magnet assisted synchronous reluctance motor (PMA-SynRM). The results can provide a reference for reducing the amount of NdFeB in rare-earth permanent magnet motors and improving the electromagnetic performance of the motors.
