Abstract: A circuit for detecting loss of phase in three-phase power systems. The circuit includes a current sensor and a microprocessor. The current sensors are coupled to respective phases of a three-phase power source configured to supply power to a load. The microprocessor is coupled to the current sensors to process current measurements and detect loss of phase in the three-phase power source.

Abstract: An alternating current (AC) motor system and control methods are provided herein. The AC motor system includes a motor having a first rated horsepower and configured to be coupled to a power source, and a drive circuit configured to be electrically coupled between the power source and the motor. The drive circuit has a second rated horsepower that is lower than the first rated horsepower.
