Abstract

To combine the advantages of permanent magnet (PM) motor and electric excitation, a hybrid excitation Vernier reluctance motor is proposed in this article. To make improved usage of working harmonics and relieve saturation effect in the stator core, a short-pitch distributed winding connection utilizing working harmonics modulated from the fifth-order harmonics of dc excitation is newly applied to this machine, and tangentially magnetized PMs are also introduced in this article. The finite element analysis (FEA) simulation results verify that the proposed winding arrangement can achieve 26% higher output torque density compared to the conventional concentrated winding distribution, and the slot PM can effectively alleviate the magnetic circuit saturation in the stator core.
