Abstract
PURPOSE: To improve response by comparing the size of the wavelength of the signal having the wavelength corresponding to motor rotary speed and that corresponsing to reference speed and determining motor current application.
CONSTITUTION: The rotary speed signal of a motor output from a frequency generator 1 is converted into a square wave signal B in a wave forming circuit 3. A pulse forming circuit 5 synchronizes with the rise of the square wave signal B and outputs a signal pulse E. A monomultivibrator synchronizes with the fall of the square wave signal B and outputs one pulse F. AND gates 6 and 9 set and rest the bistable multivibrator 7 by the AND against the pulse F and the AND of the single pulse E through the single pulse E and inverter 10 and controls the current application to the motor 2.
