The holding field of these round electromagnetic lifting magnets is less deep, which makes them especially well suited for lifting thin ferromagnetic sheets (up to 10 mm thick).
A potential problem when lifting thin sheets is that the magnetic field extends too deeply and therefore picks up two sheets at a time. The use of many small magnets with a traverse, together with a tip function in the controller, prevents this.
When using the tip function, the power to the magnet is briefly interrupted. This makes it possible to release a portion of the load, such as when moving a stack of thin sheets. It is also possible to operate with 80% of the magnet voltage. This enables you to pick up very thin sheets from a stack. After a short period of time the magnet begins operating at 100% power again to ensure the sheet is held securely during transport. To speed up the release the sheets, a brief reverse pulse is generated. This saves you valuable production time.
Electrical switching and the power supply are provided via a control box.
