Abstract
A motor load switching system in which a single motor with a single control circuit drives a plurality of different-sized loads by sequentially switching from one load to another. A parameter storage device stores a plurality of parameter sets which are optimized for respective loads. In response to a load switching command, motor control device selects a corresponding parameter set from the parameter storage device and controls the motor according to the selected parameter set. Simultaneously, a load switching device couples the motor with a new load selected from the plurality of the loads.
