Flexible and precise control options for all your adjustable speed drives and brakes
All adjustable speed drives and brakes (including Dynamatic®, Tasc® and Heenan) 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 Eddy Current Controls are available. Although there is considerable overlap of controller capability for any given drive, there are reasons for commonality at existing installations, with different features and customer benefits that continue to support the need for more than one type of controller.
To determine which Eddy Current controller model can be used with your mechanical unit, please refer to the Dynamatic® Controllers Catalog Section for the Drive/Controller Compatibility and Selection Chart. Operator devices for the controllers are specified in this section. Controllers do not include motor starters. After determining which controllers are compatible to your drive, refer to the description and specification pages on each individual controller and/or contact Dynamatic® for assistance in making your final selection.
