ABSTRACT:
There is disclosed a battery-operated motor control circuit. An adjustable voltage reference (18, 26, 28) is coupled to the battery (10), with the output of the adjustable voltage reference being coupled to the positive input of an operational amplifier (34). The negative input of the operational amplifier (34) is coupled to ratio control means (60) for setting the gain of the operational amplifier (34) and thus setting the motor (54) to a selected speed. A transistor-pair amplifier (38, 40) is coupled to the output of the operational amplifier (34), with a negative feedback line (50) being coupled from the output of the transistor amplifier to the negative input of the operational amplifier. The motor is also coupled to the output of the transistor amplifier.
