PERMA-TORK® Permanent Magnet Clutches
 

Innovative PERMA-TORK® permanent magnet clutches are capable of producing highly accurate, dependable torque—without the need of an external power source. These breakthrough clutches 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. These clutches are available in three types:

Hysteresis – Torque is infinitely adjustable, with constant torque provided independent of slip speed. This type offers the smoothest torque and longest life, making it excellent for overload and jam protection.

Key Features:

• Breakthrough permanent magnet technology requires no external control or power source
• Unique design provides torque constant or proportional with respect to speed
• Fast, precise torque adjustment
• Durable, long-lasting operation – no maintenance required
• Versatile mounting options ensure quick and easy installation
• Compact design requires minimal space
• Compatible with the MAGPOWR full line of tension controls
