Structure and working principle:

1、 Structural composition

In fact, all holding type electromagnets are sliding door holding type electromagnets. It is a direct current holding type electromagnet, and its basic principle and structure are the same for holding type electromagnets, except that the permanent magnet is placed inside the holding type electromagnet. Therefore, the support frame can stay there at the end of the schedule and maintain a certain holding force, controlling the direction of the rod's movement based on the conversion of different reverse working frequencies.

2、 Working principle

The basic principle of a holding electromagnet is similar to that of all other parallel linear moving holding electromagnets. After the capacitor is energized and excited, the guide rail slider will move towards the magnetic core due to the electromagnetic field and stop at the z-terminal position. When the power transformer is disconnected, its guide rail slider can still maintain its original position based on the electromagnetic field of the permanent magnetic field. If you want to return to the guide rail slider, try to release the working frequency or current value in the opposite direction as much as possible.
