Advantages of Electro Permanent Magnet

Application:
1. Economical,Energy saving, Environment protection
Electric permanent magnet system only use electricity at the moment of magnetic charging and demagnetization, no need power during working process, no temperature rise, save electricity power more than 95% compared with electromagnet, big reduction of using cost.
Both lifting permanent magnet and control system weights are light, can reduce the lifting equipment load,improve lifting weight.

2. High security
The magnetism of Electro permanent lifting magnet is from 2 kinds of permanent magnetic materials with different natures. Maximum magnetic force is up to 16kgf/cm2.No need electricity power during working, avoid the lifting magnet system magnetic power loss and the risk of sucked material falling down when power sudden failure or connection cable damaged. No attenuation even passed away long time, with great security during using.

3. Easy to use
Electronic control operation only have charge, demagnetization buttons, easy to operate, only use 0.1-1s for magnetization and demagnetization, improved the operation efficiency. There is no wearing parts inside the permanent magnet system, no hydraulic oil, compressed air etc., no specific maintenance, only need to ensure that the surface clean, reliable and durable, no maintenance, and practical.
After demagnetization, the surface remaining magnetic force is almost 0,even if the small magnetic particles will not adsorb on the surface of the magnetic pole, the adsorption will not scratch, will not cause remnants for the adsorption.

4. Unique, Flexible Product Design
The internal of lifting permanent magnet adopt unique modular design,dual magnetic source technology, a unique product manufacturing process, unique internal structure.

5. Perfect function
Electro Permanent Lifting magnet system is very safe, as it is not affected by power loss, no UPS battery auxiliary system. High energy from permanent magnetic materials provide lasting suction, always ensure the safety of materials and to ensure material only can be demagnetized when it is landing, provide the highest level of security to end users.

What is electro permanent magnetic technology?

Electro permanent magnet technology is via electricity to control the magnetic field lines of the permanent magnet material, which express with magnetic force(magnetized state) or non-magnetic force(demagnetized state). It is an innovative application technology that can attract or release material independently.

Magnetized state: Electromagnetic coil with instantaneous excitation current, which control the magnetic field state switching of reversible magnetic material, so that the magnetic field covering the surface of the magnetic poles and bring strong adsorption force. As the magnetic field form a closed loop,no magnetic loss, work with no heat, no noise, no energy consumption features(as shown in Figure 1.1)

Demagnetized state:in the magnetized state, the electromagnetic coil once again instantaneous excitation current, the built- in circuit to change the reversible magnetic field, so that the magnetic field converged inside the permanent magnet, and the magnetic pole surface no longer have magnetic field, the material is released( as shown in Figure 1.2)
