1. magnetic;

  • Comprise iron core, twining coil, armature unshakable in one'"'"'s determination, be positioned at the spring between armature, iron core;

    It is characterized in that material unshakable in one'"'"'s determination is the iron of cast iron or medium high carbon;

    On coil, connect a magnetic control circuit;

    The magnetic control circuit mainly is made up of timed pulsatile DC power-supply circuit, capacitor C, diode D4, resistance R 3, unidirectional conducting electronic device, capacitor discharge switching circuit, diode D4 be attempted by on the coil after resistance R 3 is connected in series, the timed pulsatile DC power-supply circuit mainly is made up of the timing switch circuit of the Rectified alternating current source circuit that is connected with coil, control Voltage pulsating direct-current supply circuit working;

    Capacitor C be attempted by on the coil after unidirectional conducting electronic device is connected in series;

    The capacitor discharge switching circuit is a relay J, and the normally-closed contact of relay J is attempted by on the unidirectional conducting electronic device, and the normally opened contact of relay J is connected between Rectified alternating current source circuit and coil.
