How Magnetic Disc Clutches Work ? Magnetic Disc Clutches consist of two opposing discs equipped with powerful rare earth magnets. The torque applied to one disc is transferred through an air gap to the other disc. Because of its simple flat design, you can have angular misalignment of up to 3° (Fig. 1) or parallel misalignment up to 1/4” (Fig. 2) and still transmit nearly full rotational torque. You can also implement an inexpensive flat barrier to separate the atmospheres or fluids surrounding the two discs. This is our simplest and most versatile application. The magnetic discs can also be parts in hysteresis brakes.

Description

Magnetic couplings offer a non-contact transfer of torque. They are typically used in pumps for seal-less applications; keeping corrosive, toxic, or flammable liquids from escaping into the atmosphere.
How Disc Couplings Work

Disc type couplings consist of two opposing discs with powerful rare earth magnets. The torque applied to one disc is transferred through an air gap to the other disc. Because of its simple flat design, you can have angular misalignment of up to 3º or parallel misalignment up to ¼” and still transmit nearly full rotational torque. You could also fabricate an inexpensive flat barrier to separate the atmospheres or fluids surrounding the two discs. This is our simplest and most versatile coupling.
