A Review on Poles Demagnetization in Permanent Magnet Motors
Mitul G. Patel
Abstract:Permanent magnet motors like BLDC and PMSM are widely used in industry and electric vehicles. Demagnetization of permanent poles in motors is the biggest problem. To design a machine that has good efficiency and no demagnetization problems, real-time fault diagnosis is necessary. Various causes of demagnetization, detection, and measuring methods are discussed by researchers analyzed in this paper. Apart from the comparison of different methods of fault detection, a general comparison among the different metho… Show more
