Sofstep® Applications Magnetic Particle Clutches and Brakes are preferred in a wide variety of torque control applications. The majority of these applications fall into three categories: Web Tensioning Closed Loop Tension Control 1. Tensioning DFP Position Sensor 2. Indexing/Cycling 3. Controlled Stop/Start 1. Tensioning Magnetic Particle Brakes provide smooth, continuous slip precisely controlled in a compact easy to mount package. The combination of Sofstep Brakes, MAGPOWR Controls and MAGPOWR Sensors allows for complete system capability. The most important point about tensioning with Magnetic Particle Brakes or Clutches is the independence of slip speed (see chart below).
