Professional Permanent Magnetic Couplings for Motor and Pump Applications
Custom Halbach Array Magnetic Couplings with High Torque Transmission
Engineered permanent magnetic couplings featuring Halbach array magnetic circuit design and high-performance magnets, delivering reliable torque transmission and leak-free operation for motor pump and industrial applications.
Product Overview
Permanent magnetic couplings are advanced non-contact power transmission devices designed for applications requiring reliable sealing, anti-vibration, and low-noise operation. Constructed with ferrite neodymium or samarium cobalt magnets arranged in Halbach arrays, they provide high flux density up to 1.4T and residual induction ≥1.2T. With customizable pull force and nickel plating surface treatment, these couplings offer stable performance across a wide operating temperature range from 80°C to 350°C.
Halbach array magnetic circuit delivers high flux density for efficient torque transmission
Wide temperature compatibility from 80°C to 350°C suitable for diverse environments
Anti-vibration and low-noise operation reduces wear and improves equipment lifespan
Customizable pull force and size to match specific application requirements
Nickel plating surface treatment provides enhanced corrosion resistance and durability
Reliable high-torque performance with coercive force ≥1250kA/m for stable operation
Versatile for motor generator and automotive applications with hermetic sealing needs
