Abstract
A method and apparatus for controlling a motor is disclosed in this application. A means for loading the motor is provided and the loading means is operatively connected to the motor. A variable drive means is operatively connected between the motor and the drive means. The variable drive means is capable of changing the loading on the motor. A sensing means is provided for actuating the variable drive means so the loading on the motor can be varied to keep the motor operating at substantially the maximum capacity of the motor.
