A Quantitative Comparison Analysis of Flux Modulation Permanent Magnet Machines with Four Topologies

Abstract

This paper presents flux modulation permanent magnet machines with four topologies, which have incorporated the magnetic gear structure and a stator within one machine. Four types of flux modulation permanent magnet machines are compared quantitatively. According to the location of the four structures, the four proposed machines are referred as motor I, motor II, motor III, and motor IV. This paper focuses on the performance comparative analysis of the four proposed machines by using finite element method (FEM). The output electromagnetic torque, induced voltage, cogging torque and efficiency of the four proposed machines have been investigated.
