Abstract

Several approaches have been developed for a better simulation of the starting and synchronous performances of an interior-type permanent magnet synchronous motor. The major feature in this study is to combine the finite element analysis with a lumped parameter model to provide desirable engineering information but at minimum computational effort. To this end, two co-ordinated stages are involved. One is to develop a unified lumped parameter model applicable for both the steady-state and dynamic analysis. The other stage is to extract individual lumped parameters from the finite element solutions. Based on the derived finite element formulae suitable for both the current source and voltage source supplies, the nonlinearity and skin effects are appropriately taken into account
