Abstract

PURPOSE: To eliminate errors due to a rotary transmission system, and to control revolution accurately, by a method wherein the rotation of a body of following revolution revolved by means of a motor through the rotary transmission system is detected, the signals and reference signals are compared and the motor is controlled.
CONSTITUTION: A DC motor 1 drives a capstan 3 of a VTR, etc. through a belt 2. A frequency generator FG4 is directly coupled with the motor 1 and a frequency generator FG5 with the capstan 3 respectively, the output of the FG5 is supplied to a reference signal frequency converting circuit 7 to which a reference signal source 6 is input, and the output of the FG4 is fed to a servo-circuit 8 with the output of the reference signal frequency converting circuit 7. Consequently, the capstan 3 can right be driven in a shape that eliminates the errors of a belt system while error detecting circuits are all made up in digital types, thus forming a circuit that is highly precise and is integrated to a high degree.
