Failure mechanisms of induction motors in the valve actuators of motor operated valves at nuclear power plants need to be investigated. It is found that motors which contain cast magnesium rotors are susceptible to cracking and melting after carrying locked rotor current. Corrosion is also a failure mechanism of the motors. A videoscope or video borescope allows a simple visual examination to be made to determine whether degradation may have occurred in in-service motors.
