Electric Controlled Permanent Magnet Excited Synchronous Machine design

Abstract

In this paper, a new type of machine – namely, the Electric Controlled Permanent Magnet Excited Synchronous Machine (ECPSM) possessing field weakening capability – is proposed and tested. The key is to incorporate a simple fixed DC coil into a stator of the machine. Thus, the resulting new type of motor can offer effective flux control. The design method of the ECPSM machine is presented in detail. By combining the use of GOT-It-software and Flux3D application for the optimization of a finite element model, the static and transient electromagnetic performances are investigated. Experimental results of the ECPSM are given to verify the validity of the proposed machine.
