Machine tool no-load self-stop power-saving circuit

The shown machine tool no-load self -stop circuit , if used on a lathe, press the button SBZ, KM is powered, the main contact is closed, the lathe motor
starts to run, and the limit switch is disconnected by the linking rod. When processing stops, move the joystick to the neutral position, and the linkage lever presses the limit
switch . At this time, the time relay KT suction table is used. If the limit switch is not reset during the KT delay time, the KT will delay When the KM coil
power supply is cut off, KM is released when the power is off, and the motor stops.
    The delay time can be determined according to the lathe operation. If the lathe is not working for a long period of time when operating the lathe, even if the motor is started and
the no-load operation exceeds the KT delay time, it will automatically stop to save electricity.
