Comparison of Methodologies for the Design of Variable Reluctance Machine

Abstract

The principles of machines design are available in several different sources; the need to proceed a simple and unified approach is based on the principles of electromagnetism. This article discusses the comparison of methods which can be applied by many manufacturers. In addition to the design of a variable reluctance machine or switched reluctance motor (SRM) using the finite element of, developed permeance networks method program can be used as a tool of verifying the design of the SRM by finite elements. The permeance networks method is based on the concept of dividing the magnetic circuit of the machine into several areas, each area is materialized by a reluctance, however, this process is laborious because the finite element method is preferable to predict the design parameters before the final verification by networks permeance.
