Abstract

This paper describes the application of dynamic reluctance mesh modelling techniques to permanent magnet (PM) machine drive modelling. The dynamic mesh reluctance model (DMRM) provides a mechanism for analysing the motor performance in significant detail, incorporating saturation and slotting effects without the slowness associated with finite element modelling. This allows the integration of the power electronic converter and control algorithms within the machine model thus making it possible to investigate the implications of machine geometry on controlled drive operation. Modelling the drive system as a whole helps for optimised machine design for controlled drive operation. In this paper a detailed machine magnetic computational model is developed, able to simulate the PM machine´s behaviour under vector control. A 4 KW PM synchronous machine is modelled using the DMRM and the results are validated using a finite element modelling software
