FSM Stator Tooth to Rotor Pole MEC Modelling and Full Machine Simulation

Abstract

This paper presents the magnetic equivalent circuit modelling (MEC) and simulation of flux switching machines (FSMs) that can be applied to a FSM with any number of rotor poles and stator teeth. The paper focuses on modelling the air-gap permeance between one rotor pole and one stator tooth and its variation with rotor position. This modular magnetic equivalent circuit (MEC) model is then used to implement a full FSM model iterating it for all the combinations of rotor poles and stator teeth in an FSM. The full MEC model is simulated and the results are compared with finite element simulations.
