  • Quiet & efficient operation
  • Wide speed ranges
  • Low maintenance with only 2 bearings
  • Easy to repair
  • Easy, drop-in replacements

What are they?

Water-cooled brakes consist of a rotating member (rotor), keyed to a straight-through double extension shaft, a stationary brake coil and an automatic water piping flow-through cooling system. The brake imposes controlled deceleration at adjustable speeds. With the Eddy Current principle of torque transmission, there is not physical contact between input and stationary members, resulting in smooth response and eliminating shock loading. Eddy Current brakes may be equipped with an optional tachometer generator mounted internally to provide a feedback signal to the brake’s controller. The controller provides the DC excitation for the brake coil. The feedback signal from the tachometer generator is compared against a reference signal within the controller to provide accurate, smooth, controlled braking or constant speed throughout the period of excitation. Constant torque can be obtained with highly accurate torque adjustments. Click here for more information on controllers for our brakes.
