Abstract
A fault control protects a pump-motor assembly from monitored faults. The pump-motor assembly includes an electrical motor mechanically coupled to a pump. The fault control determines a speed of the motor. If the speed is determined to be less than a minimum speed, the fault control generates a fault signal to affect the operation of the motor. The fault control can also determine if a phase of the power provided to the motor is missing based on vibrations sensed by a vibration transducer. The fault control can also determine temperature faults based on signals from two thermocouples, including determination of loss of inlet or discharge flow.
