Problems solved by technology

[0002] The traditional electromagnet, one type is AC power supply, which requires continuous power supply to maintain the corresponding working state during operation, but the coil consumes a lot of power when this type of electromagnet is working, which is likely to cause large heat generation and high failure rate of the coil; the other type is Pulse power supply, the electromagnet starts to work under the drive of pulse electricity, and at the same time, the magnetic retention of the working state and the continuous operation of the electromagnet are realized through the permanent magnet. After the working time is completed, the electromagnet actuator is realized through the reverse pulse electricity The reset is closed, but this type of electromagnet requires a reverse function for the pulse signal of the corresponding control terminal, and the control circuit is more complicated
