とするＤＣモータ速度制御装置。The DC motor includes a centrifugal force switch that is turned on and off according to the rotational speed of the rotor of the DC motor, and a power supply switch that supplies power to the DC motor only when the centrifugal force switch is in an on or off state, and the power supply switch is The D
The DC motor is characterized by having a short circuit that electrically connects the power supply terminals of the DC motor and allows a current due to a back electromotive force to flow between the power supply terminals while the power supply to the C motor is stopped. Motor speed control device.
