Magnetic Couplings

Magnetic Couplings consist of an outer and an inner drive. The two drives do not touch each other - the coupling works via the non-contact transfer of power, which means that the magnetic solution - in contrast to traditional solutions - does not experience any wear. The Magnetic Couplings is thus maintenance-free.

Between the two rotating units, it is possible to place a can such that two different media can be kept separate. With the hermetic enclosure of the coupling in a stainless steel housing, corrosion is avoided and the coupling can operate directly as a wet runner in different liquids and aggressive environments.

The outer drive is normally connected to the drive unit and the inner drive is, for example, connected to a pump. If a can is placed between the two contact-free rotating units, a standard air-cooled norm motor can, for example, be connected to a pump without the use of gaskets and seals.

Magnetic Couplings are also called torque couplings because they can transfer a certain maximum mechanical torque through the air. If the torque exceeds this maximum value, the coupling will "slip", which means that the rotational speed between the two coupled units is no longer the same. This prevents wear and tear and the Magnetic Couplings provides a built-in safety feature that protects against damage.

There are two main types of couplings. One type has a radial design - similar to an ordinary electric motor - while the other is axially oriented such that it can transfer forces through a surface.
