Pulse/AC Solenoid manufacturers tell you that an electromagnet is a device that generates electromagnetism when it is energized. It converts electrical energy into magnetic energy, and then from magnetic energy into kinetic energy (electrical energy → magnetic energy → kinetic energy). It is mainly to wind a conductive winding that matches its power on the outside of the iron core. This current-carrying coil is magnetic like a magnet, and it is also called an electromagnet.
Pulse/AC Solenoid manufacturers tell you that we usually make it into a bar or hoof shape to make the core easier to magnetize. In addition, in order to demagnetize the electromagnet immediately after power off, we often use soft iron or silicon steel material that demagnetizes faster. Such electromagnets are magnetic when energized, and disappear when the power is turned off. The electromagnet is widely used in our daily life, and the power of the generator has been greatly improved due to its invention.
Electromagnets can be divided into two types: DC electromagnets and AC electromagnets. Pulse/AC Solenoid manufacturers tell you that if the electromagnets are divided according to their uses, they can be mainly divided into the following five types:
1. Traction electromagnet—mainly used to pull mechanical devices, open or close various valves, and perform automatic control tasks.
2. Lifting electromagnet - used as a lifting device to lift ferromagnetic materials such as ingots, steel, iron sand, etc.
3. Braking electromagnet—mainly used to brake the motor to achieve the purpose of accurate parking.
4. Electromagnetic systems of automatic electrical appliances - such as electromagnetic systems of electromagnetic relays and contactors, electromagnetic trippers of automatic switches and operating electromagnets, etc.
5. Electromagnets for other purposes - Pulse/AC Solenoid manufacturers tell you such as electromagnetic chucks of grinders and electromagnetic vibrators.
