There are types of lifting magnet to handle heavy duty made of ferromagnetic materials, one of which is electro permanent magnet. In this article we will compare different types of lifting magnet and discuss what industry can take full advantages of it.
Common Types of Lifting Magnet
Permanent lifting magnet: This magnetic field enables the magnet to securely lift and hold heavy objects without the need for a continuous power supply.
Electromagnetic lifter: It requires a continuous supply of electric current to create and maintain the magnetic field. The lifting capacity of an electromagnetic lifter can be easily adjusted by controlling the strength of the electric current flowing through the electromagnet.
Electro permanent lifting magnet: It consists of a magnetized core like a permanent magnet, but this magnet can be activated or deactivated by an electric current, just like an electromagnet. Once activated, it can hold and lift ferromagnetic objects without the need for a continuous power supply, making it energy efficient and safe.
In These Areas Electro Permanent Lifting Magnet Is A Better Choice
Thin steel sheet moving: Electromagnetic lifter creates deep magnetic field that can penetrate several steel sheets. This might be dangerous because sometimes it attract excess sheets. Electro permanent magnet can precisely lift single or multiple steel sheets based on instruction.
Shipping port material transporting: Steel handling at shipping port requires the lifter not relying on continuous power supply to avoid risks. Electro permanent magnet, in need of power only during activation and deactivation, can keep operating during power failure.
Wind tower monopile manufacture: Monopile manufacture involves long heavy steel plate processing. Electromagnetic lifter and electro permanent lifting magnet are commonly used to handle heavy objects. However, electromagnet requires power doing operation while electro permanent magnet not, which makes the latter on more energy saving. According to statistics, electro permanent lifting magnet saves 95% electricity compared to electromagnet lifter.
Intelligent manufacture: Intelligent gantry crane is usually used to lift steel plates of different lengths and thickness. In a set of electro permanent lifting magnet, each magnet can be controlled separately. This allows the electro permanent magnets to be controlled in groups, so it is able to lift hundreds types of workpieces of disparate sizes.
Steel plate cutting: Steel plate moving and cut parts picking are essential parts in steel processing. The magnetic force of permanent magnet can’t be adjust, so it is not compatible with all sizes of steel plates. In contrast, electro permanent magnet can adapt to various sizes of steel plates according to processing needs.
