ツチ式電動ドライバ。 Using a DC power supply, connect the normally closed contacts of the relay switch and the series circuit of the motor in parallel with the series circuit of the relay coil and thyristor to operate the relay switch, and cut off the output transmission by opening the main switch. In order to do this, the normally open contacts of a three-pole main switch are connected in series, the normally open contact of the main switch is connected to the connection point of the relay switch and the motor, and the normally open contact of the relay switch is connected to one end of the motor. A clutch type electric driver has a circuit in which a clutch interlocking switch for driving the thyristor and cutting off output transmission in response to displacement of the clutch is connected to the gate circuit of the thyristor. Connect the series circuit of the resistor and relay coil in parallel to the series circuit, and connect the 2-pole main switch in series.
A clutch type electric driver characterized in that the anode of the thyristor is connected to the connection point between the resistor and the relay coil, and one end of the motor is connected to the normally closed contact of the relay switch.
