Embodiment Construction

[0034] Such as figure 1 and figure 2 A lifting electromagnet control method is shown, the coil of the lifting electromagnet 4 is connected to the three-phase power supply through a three-phase thyristor parallel circuit; the thyristor three-phase parallel circuit includes a three-phase thyristor bridge circuit I3 and Three-phase thyristor bridge circuit II2; the control method includes the following steps:

[0035] Step 1: Detect whether the magnetic suction start command is received, if yes, execute step 2, otherwise return to step 1;

[0036] Step 2: Trigger and drive the three-phase thyristor bridge circuit I3 to work in the rectification state according to the magnetic attraction start command, so that the three-phase thyristor bridge circuit I3 continuously outputs the first preset forward direction within the first preset time Voltage to both ends of the coil of the lifting electromagnet 4; the first preset voltage is 80% to 130% of the rated voltage of the lifting el...
