Adjustable speed drives, brakes and controls especially large horsepower, water-cooled Eddy Current clutches are used in the manufacture of basic raw plastics materials, performing such functions as mixing, extruding and palletizing. Smaller drives of all types can be found in the user-type manufacturing operations such as film extrusion, insulation of wire, film and parts molding operations, etc.
The needs of these industries are for large Eddy Current clutches in generally single-drive applications with simple control requirements, and smaller Eddy Current drive applications with relatively complex requirements, such as highly accurate control of speed or tension.
Dynamatic® is a very important and highly-regarded supplier to this industry, especially with respect to the larger horsepower. Eddy Current applications have proven to be highly reliable in round-the-clock operations. Customers such as DuPont have favored Dynamatic® for large mixer drives, whose process requires absolute reliability. Complete redundancy is provided by supplying two clutches, two controllers, and two closed cooling systems which can be immediately switched over to provide a backup coupling, control, or cooling system in the rare event of a breakdown, without shutting down the process.
In customer applications, Dynamatic® has the advantage of being able to respond to special needs through engineering flexibility. We are not tied to a standard mechanical design with only a limited list of available modifications; rather, we can create a system to meet the customer’s needs.
