Circuit based on consumer-market audio-amplifier chip. Stereo audio amplifier chip, connected as servoamplifier, supplies more than 1 A to motor. Amplifier used in analog configuration to supply proportional torque to motor, simpler circuits and more efficient use of energy result when utilized in pulse-width-modulation mode. Pulse-width signals generated directly by computer software or external pulse-width-modulation generator.
