Abstract
PURPOSE:To obtain the constant input and output frequency of a phase difference detecting circuit without regard to the rpn of the motor in a motor control circuit with a fail block loop, by changing the frequency division ratio of the output of the generator which is directly coupled to the motor. CONSTITUTION:The frequency of the output of an oscillator 1 is divided by a frequency divider C10, and the result is supplied to the phase difference detecting circuit 4. The output of the phase difference detecting circuit 4 passes a charging pump 6, and drives the motor 8 via an integrator 7. The frequency generator 9 is directly coupled to the motor 8, and the output of frequency generator 9 becomes the input to a waveform shaping circuit 5. The output of the waveform shaping circuit 5 becomes the inputs to a switch 12 and a frequency divider B3. The rpm of the motor 8 can be changed by the selection of the switch 12. In this case, since the frequency of the input and output of the phase difference detecting circuit 4 does not change and the integrating constant of the integrator is constant, the circuit is not required to be changed.
