Abstract

PURPOSE:To obtain a rotating speed signal with small DC drift by a method wherein a loop correcting DC drift is provided by feeding back the output signal to an input signal side in a detection circuit. CONSTITUTION:With a DC motor 2 driven by a motor driving current signal 4, the rotating speed of the motor 2 is proportional to the integral value of the motor driving current signal and a rotary angle is proportional to the integral value of a rotating speed signal. The motor driving current 4 in the motor 2 is amplified by an amplifier 15 and the output is integrated by an integrator 16 to composite a resultant rotating speed signal 22. The resultant rotating speed signal 22 is integrated by an integrator 17 with reset to obtain a resultant rotary angle signal 19. The resultant rotary angle signal 19 and the output signal corresponding to an actual rotary angle are compared by a substracter 9 and the error is supplied to integrators 17, 16 through amplifiers 13, 14. In this way, the resultant rotary angle signal 19 and resultant rotating speed signal 22 are corrected by the feedback loop supplied to the integrators 17 and 16.
