Semianalytical Framework for Synchronous Reluctance Motor Analysis Including Finite Soft-Magnetic Material Permeability

Abstract

Due to the increasing demand for high-efficiency electric motors and the maturity of vector-controlled motor drives, the Synchronous Reluctance Motor (SynRM) has received an increasing amount of attention over the past few years. Classically, SynRMs are analysed using analytical models such as presented by Vagati et al.[1]. These models require little computation time and provide the designer with significant insight into the behavior of the machine, which can be very helpful in making initial design choices. For accurate analysis of the motor performance, however, numerical methods such as Finite Element Analysis are often used, although this significantly increases the computation time per design iteration. To limit the number of FEA simulations, a systematic design procedure for SynRMs, based on a combination of analytical models and FEA simulations, was proposed by Moghaddam et al.[2].
