Systems and methods for controlling operations of a motor
First Claim
1. A method for controlling a motor comprising:
- 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;
coupling a processing device to the current sensor such that the processing device receives the at least one current signal; and
configuring the processing device to;
determine which of the plurality of power lines is active based at least partially on the at least one current signal, andgenerate a motor speed control signal that directs the motor to operate at the motor speed that corresponds to the active power line, wherein a first active power line of the plurality of power lines corresponds to a first motor speed and a second active power line of the plurality of power lines corresponds to a second motor speed.

Abstract
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.
