Problems solved by technology

[0010] 1. Unnecessary power consumption: As mentioned above, in the start-up and holding stages, the same AC voltage is passed through the excitation coil L of the conventional AC electromagnet, resulting in excessive holding power and unnecessary power loss;
[0011] 2. Heating: The evil result of unnecessary power loss is heating and heating. In severe cases, it will even burn the excitation coil L of the conventional AC electromagnet;
[0012] 3. Annoying AC noise
[0013] 4. After the AC voltage is turned on, the magnetic force generated by the exciting coil L is not strong enough, and the speed of the moving iron core M and the static iron core G is relatively slow.
[0014] 5. There is no freewheeling circuit, and the moment the AC voltage is cut off, it is easy to interfere with the external circuit
