摘要：An apparatus for detecting and controlling the rotational position of a motorwithout using a high-priced component and without requiring special softwareprocessing. The apparatus includes a motor rotation control section for selectivelyconnecting a power source to the motor to rotate the motor into a predeterminedposition, a potentiometer mechanically linked to a shaft of the motor to read theabsolute rotational position of the motor, an astable multivibrator for generating outputpulses having a duty ratio corresponding to the position read by the potentiometer, anda control signal generation section for supplying a control signal corresponding to theduty ratio of the output pulses to the motor rotation control section to control therotational position of the motor.
