DSI/Dynamatic brakes and clutches provide speed reducing capabilities Air-cooled, Adjustable Torque Eddy Current Brakes consist of a rotating member (rotor), keyed to a straight-through double extension shaft, and a stationary brake coil. The brake imposes controlled deceleration at adjustable speeds. There is no physical contact between rotating and stationary members. This results in smooth response, thereby eliminating shock loading and extending equipment life. These brakes may be equipped with an optional tachometer generator mounted externally to provide a feedback signal to the 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. Water-Cooled Eddy Current 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 Eddy Current Water-Cooled 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. This results in smooth response, thereby eliminating shock loading and extending equipment life. 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.
