Abstract: Inter-turn short circuit in permanent magnet synchronous motor, as a common fault in motor windings, can lead to interphase short circuit and even cause fires, seriously affecting the safe and stable operation of the motor. A motor model for stator inter-turn short circuit fault was established. The negative sequence component of the voltage during the fault was extracted by using double second-order generalized integration (SOGI), and the amplitude of the fault characteristic quantity was compared with the set threshold to achieve the fault diagnosis of stator inter-turn short circuit. Simulation and experimental results show that this method can accurately extract fault characteristic quantities, has the advantages of fast diagnosis speed and high precision, effectively improves the stability of motor operation, and has good application prospects and practical value.
Key words: permanent magnet synchronous motor; inter-turn short circuit; second-order generalized integration; fault diagnosis; negative sequence component
