New Electro Magnet Steel Strip Lifting Magnet with 20 Tons Capacity

What is electro permanent magnetic technology?

       Electro permanent magnet technology is an innovative marvel that uses electricity to command the magnetic field lines of permanent magnet materials. This transformative technology can either express a magnetic force (magnetized state) or a non-magnetic force (demagnetized state), enabling the independent attraction or release of materials. It stands as a pinnacle of modern technological applications.

    Magnetized State: In this state, an electromagnetic coil is instantly excited by current, masterfully controlling the switching of the magnetic field state within reversible magnetic materials. This generates a potent magnetic field that envelops the surface of the magnetic poles, delivering a powerful adsorption force. Thanks to the closed-loop design of the magnetic field, there is no magnetic loss, and it operates with zero heat, noise, or energy consumption (as shown in Figure 1.1).

    Demagnetized State: To transition from the magnetized state, the electromagnetic coil receives another burst of instantaneous excitation current. This triggers the built-in circuit to alter the reversible magnetic field, causing the magnetic field to retreat within the permanent magnet. Consequently, the surface of the magnetic poles loses their magnetic field, allowing the material to be seamlessly released (as shown in Figure 1.2).

About Electro Permanent Magnet

     The Electro Permanent Lifting Magnet system assures utmost safety. It remains unaffected by power outages or short circuits, requiring no UPS battery auxiliary system, nor any electricity during operation. The robust, enduring suction power derives from permanent magnetic materials, ensuring the steadfast security of materials, which only descend post-demagnetization by an operator, promising the highest safety standards for users.

Electro permanent magnet advantages:

1. Economical, Energy Saving, Environmentally Friendly
This cutting-edge system utilizes electrical power solely during the moments of magnetic charging and demagnetization, eliminating the need for energy during the working process. With no temperature rise, it conserves over 95% of electricity compared to electromagnets, significantly reducing operational costs.
The lightweight design of both the lifting permanent magnet and its control system alleviates the load on lifting equipment, thus enhancing lifting capacity.

2. High Security
Deriving its magnetic power from two distinct types of permanent magnetic materials, the Electro Permanent Lifting Magnet achieves an impressive maximum magnetic force of up to 16 kgf/cm2. Not relying on electricity during operation, it prevents any risk of magnetic power loss or material drops due to power failures or cable damage. Its magnetic power remains stable over time, ensuring unparalleled security.

3. Easy to Use
The simplicity of the electronic control operation, with just charge and demagnetization buttons, enhances usability. Magnetization and demagnetization occur in a swift 0.1-1 second, significantly boosting efficiency. With no wear-prone parts, hydraulic oil, or compressed air, it requires no specific maintenance—just a clean surface—ensuring reliability and durability with ease.
Upon demagnetization, the remaining surface magnetic force is nearly zero, preventing even small magnetic particles from adhering to the magnetic pole surface. This ensures the adsorption process leaves no scratches or remnants.

4. Unique, Flexible Product Design
The internal structure of the lifting permanent magnet features a distinctive modular design, dual magnetic source technology, and a proprietary product manufacturing process—culminating in a truly unique creation.

5. Perfect Functionality
The Electro Permanent Lifting Magnet system offers unrivaled safety, unaffected by power loss and requiring no UPS battery. The high energy from permanent magnetic materials ensures long-lasting suction, safeguarding materials securely until safely demagnetized upon landing, providing superior security to end users.
