<p>A method and apparatus are disclosed for improving the efficiency of operation of AC induction motors. The method and apparatus utilizes a microprocessor (13) to tune a motor control system (14) such that the time interval between the turn-on of a bi-directional switch (10) and the time of sensing the resultant inrush current through the stator is maintained substantially constant as the load is varied.</p> |
