ABSTRACT:
A circuit for controlling the rotation angle of a motor by comparing an output signal from angle setting means with the detection result from a potentiometer means which detects the rotation angle of the motor while the motor is driven in response to the output signal from the angle setting means which has: a first potentiometer for detecting the rotation angle of the motor; a second potentiometer for detecting another rotation angle at a phase different from that of the first potentiometer; an interval selecting means for selecting one of a plurality of interval signals in response to the output signal from the angle setting means; a potentiometer selecting means for selecting one of the output signals from the first and second potentiometers in response to the output signal from the interval selecting means; a compensating signal generating means for generating an offset compensating signal for compensating for an offset between a selected signal from the potentiometer selecting means and the output signal from the angle setting means; a compensating means for compensating for one of the output signal from the potentiometer selecting means and the output signal from the angle setting means in accordance with the offset compensating signal from the compensating signal generating means; and a comparing means for comparing one compensated signal and another noncompensated signal by the compensating means and for controlling the motor in accordance with a comparison result.
