Abstract
A windshield wiper motor control circuit for controlling a motor which is normally operated in either continuous or intermittent modes and wherein during the intermittent mode the motor is responsive to a voltage source controlled by a pulse generator. In response to low motor speed and voltage conditions and during overload conditions, the control circuit reverts to intermittent operation and the duration between pulses is adjusted to prevent overheating or destruction of the motor.
