Co-Axial Type Magnetic Shaft Coupling, Co-Axel Hole Type Magnetic Coupling, Rare Earth Neodymium Magnetic Drive Couplings, Coaxial Type Magnetic Permanent Motor Coupling China Supplier
Co-Axial Type Magnetic Shaft Coupling 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.
Simple Concept: Opposite Poles Attract.
This attraction is how we transmit torque from one magnetic hub to another. By driving one magnetic hub, torque is transmitted magnetically to the other magnetic hub. This can be done through the air or through a non-magnetic containment barrier such as stainless steel or fiberglass, allowing complete isolation of the inner magnetic hub from the outer magnetic hub. There are no contacting parts.
How Co-Axial Couplings Work
The co-axial coupling consists of three parts. The outer hub consists of a series of rare earth magnets that are ground, potted and attached to the inside diameter of a steel hub. The inner hub consists of a series of rare earth magnets that are ground, potted and attached to the outside diameter of a steel rotor. The inner hub is then completely sealed in stainless steel to protect the magnets and rotor from damage or corrosive substances. Typically there is a radial air gap of up to .275” (7mm) between the inner and outer hubs. Conventional bores and keyways are used to drive the inner and outer hubs.
Note: The dimensions and ratings for all co-axial type couplings are shown using NdFeB type rare earth magnets. Ratings and dimensions may vary for the SmCo versions.
Advantages of Co-Axial Type Couplings
Eliminates Rotating Seals
No Wearing Parts
Synchronous Design, No Slip at Any Speed
No Physical Contact Between Driving and Driven Parts
Custom Designs Available
MPCO Magnetic couplings are high-quality products with an extremely long service life, no maintenance and high torque transfer. They are primarily used in three different ways
1st, to transfer mechanical work to a sealed container;
2nd, to reduce the load on connected bearing systems;
3rd, as a torque limiter in, for example, gearboxes.
