Abstract

This paper focuses on the electromagnetic losses computation and comparative analysis of the proposed three topologies vernier permanent-magnet (VPM) motors by using time-stepping finite element method (TS-FEM). A dynamic core loss model of numerical analysis considering two-dimensional (2-D) magnetic properties to grasp the magnetic phenomenon inside the motors is adopted to compute the core losses of the three VPM motors. The core loss model can provide reasonable accuracy and all necessary parameters are either directly available or extracted from manufacturer-provided loss curves. The flux distribution, copper losses, core losses and efficiency of the three proposed VPM motors have been investigated, and the core loss is the important loss part of the proposed flux-modulation VPM motors.
