Magnetic Drives & Assemblies

磁传动及磁组件

Magnetic drives utilize magnetic fields between permanent magnets to achieve non-contact torque transmission — offering zero leakage, no wear, low noise, and overload protection. Gyan Drive provides magnetic couplings, magnetic gears, and custom magnetic assemblies (seals, bearings, fixtures). Ideal for chemical, pharmaceutical, vacuum, and marine applications. Magnetic circuit designs include Halbach arrays; containment shells available in 316L, Hastelloy, or PEEK.
