In recent ten years, China’s pumped storage power station has developed rapidly. As the core component of pumped storage unit, salient pole synchronous motor is very important to study its abnormal operation. In this paper, taking salient pole synchronous motor as the research object, the mathematical expressions of magnetomotive force for single-phase short circuit to ground, phase to phase short circuit and two-phase short circuit to ground are derived respectively, and the mathematical law of magnetomotive force for short circuit fault of salient pole synchronous motor under generating condition is revealed. It provides a basis for fault diagnosis, related research and calculation of salient pole synchronous motor.
