New Electro Magnet for Steel Strip Lifting, 20 Tons Round Shape

What is electro permanent magnetic technology?

       Electro permanent magnet technology ingeniously utilizes electricity to orchestrate the magnetic field trajectories of permanent magnet materials. This results in a compelling display of magnetic force when in a magnetized state, or the absence thereof when demagnetized. This groundbreaking application technology offers an unparalleled ability to independently attract or release materials.

    Magnetized state: By leveraging an electromagnetic coil with an instantaneous excitation current, the state of the magnetic field of reversible magnetic materials can be deftly controlled. This mastery allows the magnetic field to envelop the surface of the magnetic poles, generating an intense adhesive force. The magnetic field forms a closed loop with absolutely no magnetic loss, ensuring operation devoid of heat, noise, or energy consumption, as elegantly depicted in Figure 1.1.

    Demagnetized state: In the magnetized condition, another strike of instantaneous excitation current through the electromagnetic coil triggers a transformation in the reversible magnetic field, causing the magnetic field to be focused inward within the permanent magnet. Consequently, the surface of the magnetic poles becomes devoid of any magnetic field, liberating the material, as depicted in Figure 1.2.

About Electro Permanent Magnet

     The Electro Permanent Lifting Magnet system epitomizes safety and reliability, as it remains impervious to outages or power short circuits. Eliminating the need for UPS battery systems, electricity is unnecessary during operation. The system’s robust and enduring suction is derived from permanent magnetic materials, assuring the steadfast safety of the adhered materials, which can only be released by operator-mediated demagnetization. This system offers unparalleled security for users.

Electro permanent magnet advantages:

1. Economical, Energy-saving, Environmentally friendly
The electro permanent magnet system demands electrical power solely during the brief moments of magnetic charging and demagnetization, eliminating electricity requirements during the operation. This ensures zero temperature increase, conserving over 95% of electricity compared to electromagnets and drastically reducing operational expenses.
Both the lifting permanent magnet and its control system boast lightweight construction, minimizing the burden on lifting equipment and enhancing lifting capabilities.

2. High security
The electro permanent lifting magnet derives its formidable magnetism from two distinctive kinds of permanent magnetic materials. The maximum magnetic force can reach an impressive 16kgf/cm2. Since it requires no electrical power during operation, it precludes the risk of magnetic power depletion or material falling due to sudden power failures or cable damage. Its magnetic force remains undiminished over time, ensuring superior security throughout its use.

3. Easy to use
The electronic control system is intuitive, providing simple charge and demagnetization buttons. It takes merely 0.1-1 seconds to magnetize or demagnetize, enhancing operational efficiency. With no wearing components, hydraulic oil, or compressed air required, maintenance is minimal—just keep the surface clean for reliable, durable, and practical use.
Post-demagnetization, the residual magnetic force is virtually zero, preventing tiny magnetic particles from clinging to the surface of the magnetic pole. This ensures scratch-free operations and leaves no remnants behind.

4. Unique, Flexible Product Design
The internal architecture of the lifting permanent magnet showcases a unique modular design, employing dual magnetic source technology and a singular product manufacturing process, resulting in a truly unique internal structure.

5. Perfect function
The Electro Permanent Lifting Magnet system ensures supreme safety, remaining unaffected by power disruptions and requiring no UPS battery. The high energy provided by permanent magnetic materials guarantees enduring suction, ensuring the absolute safety of materials, which can only be demagnetized upon landing, thereby delivering the pinnacle of security to end users.
