The electromagnet frame push-pull type is actually based on the principle of electromagnetism, and the oil power is used to control its action and power. Push-pull electromagnets are electromagnets that push and pull. Push-pull electromagnets are one of the frame electromagnets. The function of the electromagnet is to generate magnetism through the current, summarize different magnetic coils, plus the power supply to control the size of the magnetism, the push-pull electromagnet is relatively small.

Easy to install in some small places. The iron core is magnetized by the magnetic field of the energized solenoid. The magnetized core also becomes a magnet, so that the magnetic properties of the solenoid are greatly enhanced due to the superposition of the two magnetic fields. In order to make the magnetism of the electromagnet stronger, the iron core is usually made into a hoof shape.

However, the vending machine motor drive should pay attention to the reverse direction of the coil on the hoof core, clockwise on one side and counterclockwise on the other. The magnetism of the electromagnet can be controlled by on/off current; The magnitude of the magnetism can be controlled by the strength of the current or the number of turns of the coil; The magnitude of the magnetism can also be controlled by changing the resistor to control the magnitude of the current.
