Abstract

A lumped parameter magnetic circuit model is employed to predict the influence of the finite length of a flux- switching permanent magnet machine on the electromagnetic torque. It enables performance predictions from 2-D finite element analysis to be used to analyze the electromagnetic performance with due account of end-effects. A simplified method for determining the ratio of actual torque to the torque which would be developed when end-effects are neglected is proposed. The torque predicted in this way is validated by 3-D finite element analysis.
