Focus: The lowest possible mass moment of inertia
The development of modern servomotors is in tune with the Olympic slogan "higher, faster and further" but the smaller the better. The slogan goes: Ever higher power density coupled with strong energy efficiency. Especially developers of components for servo technology are required to keep up with this development.
For shaft couplings, this implies that coupling systems must be built more and more compactly besides setting standards in terms of the lowest possible mass inertia.

Innovative function element: Universal displacement compensation on one level
When developing the Spinplus, the focus was placed on achieving the lowest possible mass moment of inertia for the coupling.
This has been obtained thanks to the unique function element manufactured through the modern MIM process, which allows for universal displacement compensation on one level. As a result, the technical advantage lies in the very short design of the coupling and high power density, combined with a minimised mass moment of inertia. In contrast to conventional multiple-disc couplings, for which universal displacement compensation is only possible in a double cardanic design, a 2nd function element with a bolt set as well as an intermediate piece is not necessary for Spinplus to enable the above-mentioned functionality.


Innovative hub design - optimised mass moment of inertia
In addition to the coupling design, which already has an optimised mass moment of inertia, the newly developed and innovative hub design highlights further optimisation of the lowest mass moment of inertia concept.  These clamp hubs reduce the mass moment of inertia significantly compared to conventional hubs.
