Built tough

With cast iron housing, brushless clutch coil, and new digital controllers, the Dynamatic® Eddy Current AS drive has what it takes to handle a variety of industrial applications. It’s ideal for operating in harsh conditions — around plaster, cement, oil, dirt, wastewater... you name it. And the standard TEFC motor allows quick washdown without interrupting continuous operation. Plus, these drives have their own internal air cooling fans, so there is need for complicated cooling systems that consume energy and can fail.

Easy to install

Dynamatic® AS drives are available for use with any three phase voltage input, which means you won’t need expensive, special wiring. They are 50/60 Hz design to simplify worldwide applications. You won’t need highly trained personnel to install these drives. In fact, they are as easy to install as electric motors. And since the controllers for Dynamatic® AS drives use only 1 percent of line power, you can place these drives up to 500 feet from their controllers. This makes them ideal for hard-to-get-at locations, such as pits, towers and on top of large machinery. You can also install them in vertical positions without expensive modifications.

Low life-cycle cost

After considering all the cost advantages — low installation cost, downtime avoided, and the minimal cost of maintenance — you’ll see how Dynamatic® AS drives are your lowest cost solution. And when used within the normal operating range on fans and pumps, their energy efficiency is equal to or better than other types of drives.

2-year warranty

We take our commitment to high quality seriously at Dynamatic®. It shows in the long life cycle our customers have come to expect from the Dynamatic® AS/FAS line. It also shows in our 24-month warranty, twice as long as most other adjustable speed drives. We also 100 percent test every controller and drive before it leaves the factory, so you can count on consistent performance.

Virtually no maintenance costs

The low maintenance requirements of Dynamatic® AS drives help you put more profit on the bottom line every year. You’ll have no slip rings or brushes to replace or clean. And the only physical connections between input and output members are four industrial bearings, needing only occasional lubrication. That’s all there is to maintaining these electromagnetic drives.

A small, simple controller

The entire SCR controller consists of one printed circuit board. And it’s interchangeable among a wide horsepower range of drives to reduce your inventory and save money.
