ABSTRACT:
A control system and method for a plurality of motors utilize one, and only one, motor drive unit that provides power to drive any one of the motors. The system and method also utilize a controller that controls which of the motors to energize. Power from the motor drive unit can be communicated to one of the motors selected by the controller, or power from a primary power source can be communicated to one or more of the motors selected by the controller. Sequencing of the motors to and from the motor drive unit and the primary power source, and between the two, is automatically controlled, such as based on how long each of the motors has been used. Accordingly, a method of controlling a plurality of motors comprises: defining a motor utilization criterion; sensing a parameter affected by the number of the motors that are operating; and sequentially starting and cumulatively operating ones of the motors selected in response to the motor utilization criterion and the sensed parameter.
