A magnetic coupling is a device that is capable of transmitting force through space without physical contact. Attractive and repulsive magnetic forces are harnessed to perform work in either a linear or rotary fashion. In its simplest form, a magnetic coupling is comprised of two components: a driver and a follower.

The driver is the portion of the mechanism connected to the prime mover (motor). Through magnetic interaction, the follower reacts to the motion of the driver, resulting in a non-contact transmission of mechanical energy. This non-contact power transmission has multiple benefits, including but not limited to:
Isolation of components
minimizes or eliminates mechanical vibrations through magnetic damping
allows for the insertion of a mechanical barrier between the driver and follower to separate environments and allow operation under pressure differentials
Highly tolerant of misalignment between the prime mover and load
Axial
Radial
Angular
Speed variation and regulation between prime mover and load

Drawings specifying the structure and dimensions of magnetic coupling are provided by the clients. Customized couplings also can be designed and processed by Feller Magnets Corp. According to customer requirements.
