The magnetic coupling generally consists of a permanent magnet rotor and a conductor rotor. There is a fixed air gap between the rotors. When the main motor drives the conductor rotor to rotate, it cuts the magnetic field lines relative to the permanent magnet installed on the driven end. During the circular motion, the conductor rotor at the active end generates an eddy current-induced magnetic field, which interacts with the permanent magnet magnetic field at the driven end, so as to realize the non-contact torque transmission between the active end and the driven end.

Magnetic Motor Coupling
Feature of magnetic coupling:
· The soft start of the motor can be realized,
· With overload protection function,
· Flexible connection, effectively eliminates system vibration,
· Low centering requirements, easy installation and debugging,
Simple structure, no need to change the foundation, easy to transform the original system,
· Maintenance-free, long service life,
· Suitable for electric power, iron and steel mining, coal, chemical industry, lifting, papermaking, textile, shipbuilding, cement and other industries with power less than 800kW prime mover.  High-Performance Magnetic Coupling Torque Transmission for Precision Machinery

Application:
It is suitable for various power equipment (power smaller than 800Kw) such as fans and pumps that are not prone to stall.

Key Advantages
Revolutionary Contactless Torque Transfer
Harnesses rare-earth neodymium magnets (NdFeB) to transmit torque across an air gap, eliminating shaft seal failures and eradicating fluid leakage in chemical/pharmaceutical processes.

Hermetic Safety Barrier
Dual containment shells (Hastelloy®/ceramic-coated optional) provide 100% physical isolation between rotating components, ensuring explosion-proof, contamination-free operation compliant with ASME BPE and FDA hygiene standards.

Lifetime Maintenance-Free Operation
Zero mechanical wear components require no lubrication, slashing 90% of upkeep costs with >100,000-hour service life.

Self-Adaptive Misalignment Compensation
Automatically accommodates ±3° angular offset and ±5mm axial displacement, reducing vibration while protecting pump/motor bearing systems.

Corrosion Immunity
316L stainless steel/zirconia ceramic construction withstands aggressive media (acids, solvents, ultra-pure chemicals) – Ideal for SEMI F40-compliant fabs.

Intelligent Efficiency Assurance
95%+ energy transfer efficiency even at variable speeds, minimizing thermal losses via patented eddy-current suppression.  OEM ODM Magnetic Pump Motor Coupling with Rare Earth Magnets
