Tension control bore brakes


General DPN

Large bore brakes from Magtrol are hysteresis brakes that contain an inside diameter that can accommodate wire feed directly through the brake, while the rotor is mounted to a tape supply reel to provide the required tension. The brakes consist of two primary parts: a pole/case assembly and a rotor.

The pole/case assembly is usually mounted in a stationary position within the machine, while the rotor is shaft mounted concentrically within the pole/case assembly. Torque is independent of speed, and is available in ratings up to 12 Nm, speed capabilities up to 3000 rpm and intermittent loads up to 2400 W.
