Abstract

PURPOSE:To obtain an excellent speed control which has no drift in rotational speed by utilizing a sample hold device with little phase delay and excellent filter characteristic. CONSTITUTION:A rotational signal of a frequency proportional to a rotational speed of a motor 1 of which the speed is to be controlled is generated and taken out by a tachometer generator 2, and one sampling pulse per one period of the rotational signal is generated in a sampling pulse generating circuit 22. A constant width pulse generating circuit 23 recieves a sampling pulse as a triggering signal, and generates a pulse of a constant width by counting clock pulses from a reference frequency signal generating circuit 21. A sawtooth wave generator circuit 5 is reset on receiving this pulse of a constant width. A sampling switch 7 transfers a voltage on a charging and discharging capacitor CS to a holding capacitor 8. A voltage on the holding capacitor CS is applied on the motor 1 through a motor driving circuit 12.
