Abstract

The permanent magnet motor mainly uses the permanent magnet excitation, the motor fault will affect the excitation performance of the permanent magnet, thus affecting the performance of the entire motor, serious stator inter-turn short circuit fault will cause short circuit between phases, causing three-phase current imbalance, resulting in increased harmonic magnetic field, rotor temperature rise. In this paper, the 5kW permanent magnet synchronous motor in 200mm shaftless rimless thruster is taken as the research object, and the single-phase two-slot inter-turn short circuit and two-phase inter-turn short circuit are analyzed. The Ansoft finite element analysis software is used to analyze the influence on the motor by setting two kinds of winding faults, which provides a reference for the fault diagnosis of synchronous motor.
