ABSTRACT:
A direct-current motor is energized through a diode in the emitter-base network of a transistor and through the emitter-collector network of another transistor which is held conductive by the driving current but which automatically limits the current flow through the motor. When the circuit is de-energized, a self-braking effect is established by the circuit which is substantially symmetrical for reversing operation of the motor.
