Metau magnetic couplings are permanent-magnet synchronous couplings. They enable contactless, synchronized transmission of torque between two shafts without mechanical contact or friction. The magnets are arranged so that they generate a common magnetic field, allowing the shafts to rotate at exactly the same speed. This contactless transmission makes them an extremely reliable solution, particularly for demanding industrial applications.
