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.
