To solve the problem that it is difficult to accurately identify the rotor eccentric fault. demagnetization fault and hybrid fault of a permanent magnet synchronous motor (PMSM) with a slot pole ratio of 3/2 and several times of it. this paper proposes a method to identify the rotor fault based on the combination of branch current analysis and a machine learning algorithm.
