。According to the above configuration, when the power source 2 is equal to the rated voltage of the motor 8, the capacitor 4 is short-circuited by the switch 6, resulting in the circuit shown in FIG. This circuit is the same as the conventional capacitor speed adjustment circuit, and when the speed selector switch 9 is connected to terminal 10-1, high speed rotation is achieved, and when terminals 10-2 and 10-3 are connected, high speed rotation is achieved.
It is connected to a capacitor 6.7 that can adjust the speed and speed. Terminal 10-4 is a stop terminal. When the power source 2 has a potential higher than the rated voltage of the motor 8, the switch 6 is opened and the voltage applied to the motor 8 is reduced to the rated value of the motor 8 by the capacitor 4. The circuit is shown in FIG.

It is sufficient to step down the voltage by using multiple capacitors, and more speed adjustments can be made by increasing the number of regulating capacitors.0 Effects of the Invention According to the present invention, the voltage applied to the motor is controlled by the capacitor. However, since the speed adjustment is also done by a capacitor,
There is no need for a transformer, the regulator can be made smaller, and there is no need to worry about heat generation. In addition, it is possible to configure a speed regulator that can easily accommodate various types of power supply voltages simply by changing the capacitance of the capacitor, and can also accommodate speed regulation by changing the capacitance.
