摘　　要：磁通切换型磁阻电机可采用不同的励磁形式,其中电励磁式与混合励磁式的励磁磁动势是可调节的,在单相电励磁结构基础上分析设计了相同定转子极数比的并联混合励磁的磁通切换型磁阻电机。提出一种借助于变跨距电励磁磁通切换型磁阻电机的有限元仿真结果,以建立混合励磁结构的简化磁路模型的方法,通过该模型可获得描述电机动态特性的非线性等效励磁电流、电感等参数。制作了具有可比性的电励磁、混合励磁结构样机各一台,并进行了实验测试,模型计算值与实验值吻合度较高,验证了理论分析、建模方法的正确性。Flux switching motor（FSM） can adopt different excitation forms,and the excitation magnetomo-tive force of both electrical excitation structure and hybrid excitation structure is adjustable. Based on an-alyzing the single - phase FSM, a parallel hybrid excitation flux switching motor（ HEFSM） was intro-duced. 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 induct-ance. 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.
