Hysteresis Brakes

Torque is proportional to input current, and independent of RPM. Torque is especially smooth, even at near-zero RPM. Also good for light tension / high RPM applications, due to good heat dissipation ratings. All models except H3 have the Cog-Buster which keeps slip torque smooth.

Typical Applications
  • Producing tension for unwinding wire, fiber optic cable, and narrow webs.
  • Load simulation for testing electric motors.
  • Light tension / high RPM applications
Torque
  • Is proportional to input current.
  • Is independent of RPM.
  • Is especially smooth, even at near-zero RPM.
  • Brake Torque Range 0.04 to 2.5 oz-in (9 to 250 oz-in)
  • Metric Unit  – Brake Torque Range = 0.03-1.77 to 6.3-177 Newton-cm
