Abstract

<p>  In recent years, electrification has been promoted as part of the measures toward global warming, and demand for power-saving and high-efficiency motors is increasing. Among the various types of motors, permanent magnet synchronous motors (PMSMs) are used in various fields, such as electric vehicles and home appliances. However, PMSMs have issues with mechanical strength and cost. In comparison, flux reversal motors (FRMs) have a simple reluctance rotor, and a stator with armature windings and permanent magnets. Due to the high torque density of FRMs the same as PMSMs, they are expected to be used in multiple applications such as for electric vehicles and wind power generations. However, the conventional FRM has a problem with large eddy current loss in magnets. This paper presents a novel FRM with a cross-shaped stator pole that reduces the eddy current loss. The usefulness of the proposed FRM is proved by a three-dimensional finite element method (3D-FEM).</p>
