In this paper, a permanent magnet vernier motor (PMVM) topology with flux barriers that can suppress the permanent magnet eddy current (EC) loss is proposed. Through the combination of theoretical analysis and finite element analysis (FEA), it is revealed that flux barriers can suppress permanent magnet eddy current loss by reducing the amplitude of the modulated harmonic flux density. By establishing a series of finite element analysis models of permanent magnet vernier motors and permanent magnet synchronous motors (PMSMs), it is verified that flux barriers can greatly reduce the permanent magnet eddy current loss and iron loss while having less effect on the torque. The influence of flux barriers on the torque and loss of the motors with different motor types and different slot-pole combinations under different working conditions is compared, and the influence of flux barrier width variation on torque and loss is studied. Finally, the application of flux barriers in different type vernier motors and different operating conditions is summarized.
