ABSTRACT:
A dc motor speed control circuit is provided. A first circuit utilizing an opto-electric sensor for providing an input signal corresponding to a desired dc motor speed is connected to a second circuit and the second circuit is connected to the dc motor, wherein the second circuit responds to the input signal and causes current to flow through the dc motor corresponding to the input signal. A temperature circuit, voltage level circuit and current level circuit may also be connected to the second circuit to control the dc motor.
