Abstract :
The negative-sequence current analysis is a classical method of single phase winding short in the PMSM. In this paper, a simple method is presented for on-line winding short circuit fault detection. It consists of a new calculation of negative sequence current based on negative-rotating synchronous reference frame. The amplitude of negative-sequence current is used as the indicator reflecting the severity of inter-short fault. The fault-detecting method is implemented very easily for electric driving system based on vector space control. A simulation is presented to verify the application proposed method.
