Hysteresis Brake - Specifications

Torque range  =  0.03-1.77  to  6.3-177 Newton-cm.

View in inch units

Hysteresis Brake Photo   Characteristics - 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. Also - load simulation for testing electric motors.

Exceptionally Stable & Reliable - Since torque is produced magnetically, across an air gap.
