Abstract

This paper presents the simulation and experimental results of a five-phase squirrel-cage induction motor. The new machine has been designed to operate in a drive system with third harmonic rotor flux injection in order to improve the motor torque utilization. The motor structure, the mathematical model as well as the laboratory prototype have been described. The motor speed-torque characteristics and transients are elaborated on. Furthermore, the start-up possibility in the case of one or two stator winding faults has been shown as well. The idea of a closed loop speed control with increased load torque is presented.
