Abstract :
This paper aims to determine the optimal values of time and space harmonics used in the frequency-based analytical model for better detection of permanent magnet demagnetization fault in axial flux permanent magnet synchronous machines. The design optimization algorithm is based on a stochastic Cramer-Rao lower bound technique.
