Abstract :
A stator turn fault in a symmetrical three-phase machine cause a large circulating current to flow and subsequently generated excessive heat in shorted turns, generate irregular control current of the three phase leads to demagnetization. In this paper, the effect of the circulating current in shorted turns on the demagnetization of PM and motor performance is analyzed by using FE analysis.
