Magnetic Drum Coupling Contactless Torque Transmission Item No. HS-PMC  series

Classic drum magnetic coupling provides interruption-free torque transmission without any contact between drive and driven parts, making them suitable for applications where product contamination must be avoided such as food, beverage, and pharmaceutical industries.

The rotor is a cold-rolled steel shaft that is powder-coated to high corrosion resistance. It is precisely fitted into the isolating cover and aligned correctly.
The isolating cover is a molded polypropylene disc that is fitted between the internal rotor and rotor. It keeps air out of the system while allowing the magnetic field to pass through it.
The internal rotor is a range of permanent magnets located in the internal face of the drive wheel which rotates within the isolating cover.
The Drive wheel (Stator) is a series of rare earth magnets located in the drive wheel whose poles are positioned to interact with those of the internal rotor to produce force/torque transmission while also providing a self-alignment function.

We offer 3 types of classic magnetic coupling:
Unthreaded Hole Type
Axel Hole Type
Flange Type

Operating environment
A high level of corrosion resistance is necessary throughout the assemblies in harsh conditions. This covers the coating or plating of the magnets as well as the ability of other non-magnetic parts to resist corrosion. Classic Drum Magnetic Coupling

Operating temperature
Temperature has impact on magnets characters. Working temperature range has to be taken into consideration during the design of the assemblies, such as magnet materials (e.g. NdFeB or SmCo) and grades selection. The thermal properties of the non-magnetic components are also the thing you need to think of.

Magnetic field optimization
Because the density and force of the magnetic field is not linear with the distance, this requires our experienced software engineers to design, simulate and verify with reliable software.

Machining difficulties
Those experienced in magnets manufacturing may not be good at machining the non-magnetic parts (such as refractory metals, stainless steel, copper, aluminum and their alloys, etc.) into complex shapes with tight tolerances. Meanwhile, the manufacturer of non-magnetic products barely know about the technical details of magnets. EPI is such an excellent magnetic assembly supplier with the very vertically integrated capabilities on magnets production and non-magnetic materials machining to provide a professional service with quality controlling, quick response, cost reduction and shortened lead times.  Torque Limited Anti Iron Powder Type Magnetic Couplings

Assemble difficulties
Neodymium magnets are known to be extremely difficult to be fixed in place for assembly. As an example, assembling powerful neodymium magnets to a rotor or yoke requires various adhesives. Without well-designed assembly fixtures, it may result in improper adhesion of magnets to other parts, poor glue bonding, magnet malposition, or magnet demagnetization during the curing process. This will cause higher defect rates, higher costs, and lower efficiency in the finished products.  Fixed Speed Torque Limited Braking Magnetic Couplings
