Performance analysis of linear permanent magnet Vernier machine using mixed subdomain and magnetic equivalent circuit techniques including end‐effect

Performance analysis of a linear permanent magnet Vernier machine (LPMVM), which has complex structure, is mostly based on the finite element methods, while for its optimisation or sensitivity quick mathematical technique desirable. This paper introduces an LPMVM and principles operation. Then, mixed subdomain magnetic equivalent circuit are applied to extract field equations in various parts machine, end-effect included. Besides, electromotive force, thrust normal force electric determined. An was prototyped tested verify accuracy proposed method.
