Electro-permanent magnetic lifting tool is equipment for material handling based on electro-permanent magnet technology. Its working principle is a clever combination of the properties of permanent magnetic materials and electromagnetic theory.

An electro-permanent magnetic lifting tool mainly consists of permanent magnets and electromagnetic coils. The permanent magnets supply strong and lasting magnetic force, while the electromagnetic coils are used to control the activation and deactivation of magnetic force.

Before lifting operation, electric current is applied to the electromagnetic coils to generate a magnetic field opposite to that of the permanent magnets. This counteracts the magnetic force of permanent magnets and keeps the lifting tool in non-magnetic state, so it can be conveniently placed above the materials to be lifted.

When material adsorption is needed, cut off the current of electromagnetic coils. The magnetic force of permanent magnets will no longer be offset, and the powerful magnetic force can firmly grip the materials for lifting.

The unique feature of the electro-permanent magnetic lifting tool is that its magnetic force can be precisely adjusted by controlling the current. It can not only guarantee sufficient lifting capacity but also prevent damage to workpieces. Meanwhile, the magnetic force can be maintained even in case of power failure, ensuring safety and stability during lifting.

Thanks to this working principle, electro-permanent magnetic lifting tools have many advantages such as high efficiency, energy saving, safety and reliability, and are widely applied in modern industrial lifting fields.
