Abstract

Synchronous reluctance machine with a conventional rotor structure and a 3-phase auxiliary winding attached to a balanced capacitance for power factor improvement will find application in high speed , high power drives. This paper presents an understanding of its operation using the electromagnetic as well as the electric circuit concepts. Analytical and simulation results of this machine configuration show that the torque as well as the power factor performance is better compared to conventional reluctance machine.
