Carotron now offers products by Drive Source International, Inc. or DSI/Dynamatic®, formerly Eaton Dynamatic.  DSI/Dynamatic® is a manufacturer of Dynamatic® brand products, parts and services that stocks thousands of products and parts, including Eddy-current drives, factory-warrantied replacement parts.  DSI/Dynamatic® also provides an environmentally-friendly alternative through its preventative maintenance program, remanufacturing services, and upgraded digital controls for all brands of vintage Eddy-current drives.

Eddy-current drives help narrow the field when choosing a drive if you need to minimize the cost of downtime.  Why?  No other drive technology operates with such simplicity, with so few parts to wear out…and with minimal maintenance.  Many engineers and designers prefer eddy-current drives due to the long-term savings.

*Automotive:  Test stands for measuring and controlling torque, speed and horsepower (input and output), of a manufacturer’s product.

*Chain Conveyors:  Many chain-type conveyors that are utilized automotive and coating plants require adjustable speed for acceleration and deceleration control, product transfer, general production rate control and controlling specific product operations (dyeing, painting, dipping, etc.)  

*High Torque:  Eddy-current drives are well suited for high-torque applications because they can provide high torque over a wide speed range.  

*Tension Control & Winder:  The simple, flexible speed adjustment and control qualities of the Dynamatic® Eddy-Current provides an accurate and inexpensive means of tension control and winder applications.
