Abstract Permanent magnet synchronous motor (PMSM) is widely used in different fields because of its simple structure, stable operation, high efficiency and various shapes. During the use of the PMSM, various faults will inevitably occur, such as the demagnetization fault, the circuit fault, the rotor eccentricity fault, the bearing fault and so on. Based on the structure and working principle of the PMSM, the causes and diagnosis methods of various faults were summarized, and the advantages of model construction and signal processing in fault diagnosis were analyzed. The research results provide a certain theoretical basis for the fault diagnosis of PMSMs.
