Current Harmonics of a Current Superimposition Variable Flux Reluctance Motor

Abstract

We propose a current superimposition variable flux reluctance motor, which consists of 6 phases. This motor is driven using a 3-phase vector control because the 6 phases consists of 2 sets of 3 phases. However, the phase current contains harmonics because the 3-phase vector control is applied to composition currents. In this paper, a control method to reduce the copper losses is proposed. The torque generation mechanism focusing attraction forces are described. Finally, the influence of the current harmonics on the torque and copper loss is investigated.
