Abstract

Abstract: Multi-phase machines (more than three-phase) are rigorously being investigated for various high power applications due to their increased power to weight ratio, increased frequency and reduced magnitude of torque pulsation, and fault tolerant characteristics. Fault analysis of a system is extremely important, not only to understand its operating characteristic, but it is also required prior to the design of suitable control/protective scheme. Therefore, the aim of this paper is not to devise a new mathematical model and control algorithm, but to investigate the behavior of six-phase synchronous motor (SPSM) under fault conditions caused by open circuit (OC) and short circuit (SC) at its input terminals as that has not been reported so far. Some key analytical results have been experimentally verified.

Key words: Six-phase synchronous motor, phase redundancy, open circuit, short circuit.
