回路。 ［’ ｔ−A starting switch and a power holding switch are connected in parallel between the power supply and the motor, and the starting switch is first turned on to start the motor, then the power holding switch is closed, and then the starting switch is opened. Is it possible to use only the power hold switch? In a motor drive circuit configured to hold power, a voltage drop element is connected in series with a power hold switch, and the series circuit of the power hold switch and the drop element is connected in parallel to the starting switch. At the same time, connect a switching element in parallel with the motor,
When the starting switch is turned on, the switching element turns on and outputs a muting voltage, but when the starting switch is opened, the voltage drop element receives the power supplied via the power holding switch and the voltage drop element. A motor drive circuit characterized in that the circuit is connected to turn off and stop the muting voltage due to a voltage drop caused by the voltage drop. ['t-
