Abstract

PURPOSE: To perform a constant speed control without adding a unit for detecting a speed by controlling constant speed by detecting a pulse generated from a commutator of a DC motor.
CONSTITUTION: When a DC motor 4 rotates, a current flowed to the motor 4 is varied at the seam of the commutator to generate a short pulse. A pulse detector 6 detects the pulse and applies it to a frequency/voltage converter 7. A speed controller 5 controls the motor 4 in response to a deviation between a set speed and the speed signal from the converter 7. Thus, the size can be reduced.
