1. Brake electromagnet: used for mechanical braking of the motor in the electric transmission device to achieve the purpose of accurate and rapid stop. The common models are mzd 1 (single phase) and mzs 1 (three phase) series.

2. Lifting electromagnet: used as lifting equipment to lift magnetic materials such as steel and iron ore, or used as electromagnetic manipulator to fix magnetic materials such as steel.

3. Solenoid valve: Use magnetic force to push the solenoid valve to open, close or reverse the valve port.

4. Traction electromagnet: The traction mechanism is mainly used to perform automatic control tasks.

Advantages of electromagnet:

Whether the magnetism of electromagnet can be controlled by on-off current; The magnitude of magnetic force can be controlled by the strength of current or the number of turns of coil; The magnetic field can also be controlled by changing the resistance to control the current; Its magnetic pole can be controlled by changing the direction of current, and so on.

That is, the strength of magnetism can be changed, the presence or absence of magnetism can be controlled, the direction of magnetic poles can be changed, and magnetism can disappear due to the disappearance of current.
