SYSTEMS AND METHODS FOR CONTROLLING OPERATIONS OF A MOTOR

摘要

A method for controlling a motor is described. The method includes configuring a current sensor to sense a current supplied to the motor from at least one of a plurality of power lines and to generate at least one current signal indicative of the sensed current. The method also includes coupling a processing device to the current sensor such that the processing device receives the current signal. The method also includes configuring the processing device to determine which of the plurality of power lines is active based at least partially on the current signal and generate a motor speed control signal that directs the motor to operate at the motor speed that corresponds to the active power line.
