A Comparative Analysis for a Flux-Modulated Permanent-Magnet Motor with an Improved Structure
This paper introduces a flux-modulated (FM) permanent magnet motor with an improved structure.The conduction iron segments which plays flux-modulated role exist in the air gap between rotor and stator for the original FM motor.But by artfully integrating the any number of flux-modulated iron teeth which can adjust space harmonic of the air-gap magnetic field in every stator pole,the novel motor can readily achieve the high torque output at low speed.And then by using the time-stepping finite-element method (FEM),the basic characteristics,cogging torque,torque angle and core loss are analyzed.The theoretical analysis and simulation results show that the proposed motor can not only retain the advantages of original motor,but also have other merits.
