Abstract :
A simple stator fault detector for AC motors, based on the TMC320C243 DSP controller is presented. The detector provides compensation of the constructional and supply voltage imbalances, and senses the ripple of the compensated instantaneous power. The power ripple is indicative of such stator faults as open and short circuits in the stator winding. The low-cost detector is expected to give an early warning of an impending stator failure in inexpensive industrial and domestic AC motor drives. Details of implementation and results of experimental investigation are described
