Fast, precise torque adjustment. Durable, long-lasting operation – no maintenance required

Perma-Tork® Permanent Magnet Clutches Overview

Smooth, precise control is the objective of all clutches and brakes. MAGPOWR’s innovative Perma-Tork® permanent magnet clutches are capable of producing highly accurate, dependable torque, without the need of an external power source. The clutches (available in hysteresis or magnetic particle) use high-energy, multi-pole magnets to establish lines of magnetic force that retard the motion of the center rotating disc, delivering smooth, precise control.

Designed for long-lasting, reliable performance, Perma-Tork clutches are commonly used in light torque control applications, including tensioning, torque limiting, magnetic coupling and testing.
