Eddy-Current Controls For All Make & Models

Dynamatic®, Tasc®, Heenan and all adjustable speed drives and brakes require a separate controller to provide the DC excitation for their coil. A feedback signal from an internal tachometer generator is compared to a reference signal within the controller to maintain accurate speed control. Many different controllers are available. Although there is considerable overlap of controller capability for any given drive, there are reasons of commonality at existing installations, different features and customer benefits that continue to support the need for more than one type of controller. Operator devices for the controllers are as specified in this section. These controllers do not include motor starters. Please refer to the Dynamatic® Controllers Catalog Section pages for the Drive/Controller Compatibility and Selection Chart that show which controller model can be used with the mechanical units. After determining which controllers are compatible to your drive, refer to the description and specification pages on each individual controller and/or Contact Drive Source International, Inc. for assistance in making your final selection.
