Modeling and Design Optimization of an Axial Circumferential E-type Linear Rotary Switched Reluctance Motor

Accurate modeling and rapid optimal motor design are critical to meet modern industrial requirements while balancing manufacturing burdens. In this paper, an axial circumferential E-type linear rotary switched reluctance motor (ACE-LRSRM) with limited volume, multiple motion modes and high-power density performance is proposed. First, the ACE-LRSRM structure is introduced, and the operation principles of the motor in different modes are analyzed. Afterward, the equivalent magnetic circuit method is introduced to improve the parameter-solving process of the Maxwell tensor method, and a mathematical model of the ACE- LRSRM is established to analyze the electromagnetic characteristics of the motor in linear and nonlinear cases. Additionally, Technique for Order of Preference by Similarity to Ideal Solution is used to optimize the multiobjective design of the motor and improve its target performance. Finally, the validity of the modeling and design optimization of the ACE-LRSRM is verified through comparative finite element analysis.
