Dual motor drives for PMSM using average phase current technique

Abstract

Dual motor drives designs are attractive for high power application because of their mechanical simplicity, traction and regenerative braking control on low friction surfaces. However, such configurations normally require two power inverters with coordinated control. The high cost and large size of packaging needs of the inverters make such dual inverter, dual motor drive configurations economically less competitive. Therefore, the need for dual motor drives fed by single inverter rising consequently to reduce sizes and costs with respect to the single motor drives, either in industrial or in traction application. This paper aims to investigate the behavior of dual motor drives fed by single inverter using averaging technique. MATLAB/Simulink has been chosen as the simulation tools. And the averaging technique that has been used is mean phase current method. The results show that the technique that has been applied gives the significant responses due to reference value given.
