Abstract
PURPOSE:To reduce the fluctuation of the amount of state, by a method wherein the rotating position of a rotating body is detected by a rotating position detecting means upon the transition of the renewal operation of a stored value reserving means while the digital stored value of the reserving means, which is corresponding to the rotating position, is renewed and reserved. CONSTITUTION:A 3-phase brushless motor 1 for a video recorder drives directly the rotations of a rotating sensor 2 and a load 10. 3-phase position detecting signals h1-h3 are obtained by 3 sets of position detecting elements and an AC signal (a), accompanied by the rotation of the rotation sensor 2, is generated and inputted into a compensator 4 through a speed detector 3 and the like. The compensator 4 is constituted of an operator 5, a memory 6, a D/A converter 7 and a rotating position detector 8 and operates the digital signal (b) of the speed detector 3 to output a control signal (c). A speed control system is constituted of said motor 1, the rotation sensor 2, the speed detector 3, the compensator 4 and a driver 9 and the rotating speed may be controlled at a predetermined value.
