Abstract

PURPOSE:To accomplish a stable speed control even at an extremely low speed while enabling a program control by driving a motor to be controlled moving stopping target positions successively with the application of a stop servo to the motor. CONSTITUTION:Sine wave signals Sb and Sa are produced as phase shifter by 90 deg. to each with two magnetic heads 5 and 6 of frequency generator 3 connected to a motor 1 to be controlled and inputted into multipliers 9 and 10. According to a programing signal Sp, signals Ka and Kb outputted from a control signal generation circuit 11 are inputted to the multipliers 9 and 10 to be multiplied by the sine wave signals Sa and Sb and a signal Sc is obtained by addition. Here, the signals Ka and Kb are varied timewise so that the signal Sc takes form of a sine wave with the zero point moving. The Sc is inputted into a comparator 13 and compared with a zero potential to control a driving circuit 16 of a stop servo with the deviation thus obtained.
