What is Magnetic Disc Couplers ?
Magnetic disc couplers provide a contactless means of torque transfer. They are predominantly utilized in pumps for applications requiring seal-less operation, thereby preventing the escape of corrosive, toxic, or flammable liquids into the atmosphere.
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.
Understanding magnetic disc couplers
Magnetic disc couplers are composed of two opposing discs that incorporate powerful rare earth magnets. Torque applied to one disc is conveyed across an air gap to the other disc. Thanks to their simple, flat design, these couplings can accommodate angular misalignment of up to 3 degrees or parallel misalignment of up to 1/4 inch while still transmitting a significant portion of the rotational torque. Moreover, an affordable flat barrier can be fabricated to separate the atmospheres or fluids surrounding the two discs.
