ABSTRACT:
An SCR motor speed control system having a capacitor for triggering the SCR into conduction is provided with circuitry for limiting the top speed of the motor by sensing the armature back EMF generated during the non-conducting period of the SCR to determine the motor speed. When the speed is above a predetermined threshold value, a transistor is turned on to short circuit the charging path of the capacitor.
