Modeling and analysis of single-phase parallel hybrid excitation flux switching motor

Flux switching motor( FSM) can adopt different excitation forms,and the excitation magnetomotive force of both electrical excitation structure and hybrid excitation structure is adjustable. Based on analyzing the single- phase FSM,a parallel hybrid excitation flux switching motor( HEFSM) was introduced. It has same number of stator and rotor pole with the FSM. According to the finite element analysis result of a FSM model which has an unusual winding span,a method of building the HEFSM's simplified magnetic circuit model was provided. Through the model,some nonlinear parameters to describing the dynamic characteristics of the HEFSM were obtained,such as equivalent excitation current and inductance. The prototype of both FSM and HEFSM were manufactured,and the comparability experiments were carried out. The calculation data closely match the experiment data; it shows that the theory analysis and modeling method are correct.
