Permanent Magnetic Coupling（Standard Type）

Permanent Magnet Couplings （Standard Type）– Contactless Power Transmission for Industrial Efficiency

JM Permanent Magnet Couplings (PMCs) revolutionize mechanical power transmission by replacing traditional physical connections with a non-contact air gap between the motor and driven load. Utilizing the magnetic interaction between high-performance permanent magnets and copper conductors, torque is transferred across the air gap—without mechanical wear or friction. The smaller the air gap, the higher the torque transmission, forming the core principle of PMC technology.

After years of R&D, JM has optimized air gap adjustment, magnet quantity, and magnetic strength to deliver a wide range of PMC models tailored to diverse industrial needs. JM permanent magnet couplings stand out for their high efficiency, energy savings, environmental safety, and reliability, making them an ideal replacement for hydraulic couplings and variable frequency drives (VFDs). They provide soft start, torque limiting, and speed adjustment—ensuring smooth, trouble-free operation for your equipment.
