Performance Evaluation of a Current Superimposition Variable Flux Machine Using Permanent Magnets

Abstract

A current superimposition variable flux machine using permanent magnets that can control its torque constant has been proposed. This machine aims to improve the efficiency of the current superimposition variable flux reluctance machine by using permanent magnets. In this paper, the computed characteristics by carrying out measurements on a prototype are verified. The structure and operational principle of this machine are described. First, the cogging torque and EMF are measured. Finally, the N-T characteristics are measured under vector control.
