Abstract

PURPOSE: To make an adjustment at one place for making speed variable by imposing modulation on the time constant or base voltage of a conversion circuit for converting a feedback signal into voltage in proportion to the output in the base signal system output from a base oscillating portion.
CONSTITUTION: A phase difference-voltage conversion circuit 5 outputs voltage in proportion to the phase difference between the output in the base signal sytem output from the base oscillating portion 1 and the feedback signal from a motor portion 13. The voltage conversion circuit 29 converts the output in the base signal system into voltage, and a modulation circuit 32 imposes modulation on the time constant of a feedback signal frequency-voltage conversion circuit 31 in proportion to the output voltage of the voltage conversion circuit 29. The output of the phase difference-voltage conversion circuit 5, the feedback signal frequency-voltage conversion circuit 31 and base voltage circuit 10 is synthesized and it is given to the motor 13 through a motor driving circuit 12.
