Dynamic simulation of PM motor drive system based on reluctance network analysis

This paper presents a method for dynamic simulation of a permanent magnet (PM) motor including its drive circuit based on reluctance network analysis (RNA). The RNA, which is based on the magnetic circuit method, has some advantages for simulating electric motors as follow: simple analytical model, high calculation accuracy, and easy to combine with external electric circuits, motion and thermal dynamics. First, the basis of the magnetic circuit method is described briefly. Next, a case study of dynamic simulation of a PM motor drive system is presented. The validity of the proposed method is proved by comparison with experimental results.
