What are magnetic disc couplings ?

Magnetic disc couplings provide a contactless means of torque transfer. The concept is straightforward: Opposite poles attract. This fundamental principle enables the transmission of torque from one magnetic hub to another. By rotating one magnetic hub, the torque is magnetically conveyed to the companion hub. This transmission can occur through air or via a non-magnetic barrier like stainless steel or fiberglass, achieving complete isolation of the inner from the outer hub. The design excludes any contacting components.
What makes magnetic disc couplings so efficient?

All sizes of CCmagnetics' magnetic disc couplings use sector-shaped magnets for torque transfer. These magnets maximize the use of the disc surface area, eliminating redundancy. The image above, captured using magnetic field viewing film, illustrates this point by showing the magnetic field distribution within a CCmagnetics magnetic disc coupling.
Compared to the Demo magnetic disc coupling, CCmagnetics' magnetic coupling is smaller and lighter while achieving greater torque.This disc-shaped magnetic coupling is not only more efficient but also saves valuable space within the device.

Good quailty.It can transmit without any issue during coupling even if there is a bulkhead between them, as long as the bulkhead is made of non-magnetic material.
