DYNAMATIC® “AS” DRIVE: Here’s What Makes a World Leader.
Here’s performance at its
best in the .75-40 hp adjustable speed drive class. Smooth, responsive, and
highly reliable. The Dynamatic® Eddy-Current “AS” drive with tachometer
feedback lets you control speed within 1/2 percent for load changes from no
load to full load. You also get a full 34 to 1 speed range at 250 percent of
rated torque — great for starting and momentary overload conditions.
PLC Compatible
Interfacing the Dynamatic® “AS” drive to computer control systems is a snap. The Controller interfaces easily with PLC systems.
Designed for Reliable Performance
A look inside the Dynamatic® “AS” drive tells you why it’s destined to lead the way for adjustable speed drives. Nothing could be simpler yet offer such high performance and reliability. With magnetic transfer of power and just four bearings, this unique design has very few points of friction. Which means more reliable performance — an advantage that manufacturers with continuous operations find especially important.
Built Tough
With cast iron housing, brushless clutch coil, and solid-state controller, the Dynamatic® Eddy-Current “AS” drive has what it takes to handle a variety of industrial application, it’s ideal for harsh conditions — around plaster, cement, oil, dirt, wastewater, you name it. And the optional TEFC motor allows quick washdown without interrupting continuous operation. And these drives have their own internal air cooling fans, so there is need for complicated cooling systems that can fail.

The Dynamatic® “AS” drives are available for use with any three-phase voltage input, which means you won’t need expensive, special wiring. They are available in 50, 60 and 50/60 Hz units 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.
Virtually No Maintenance Costs
The minimal maintenance of the Dynamatic® “AS” drives can 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 new drives.
A Small, Simple Controller
The entire solid-state controller consists of one printed circuit board. And it’s interchangeable among a wide range of drive horsepower to reduce your inventory and save money.
Low Life-Cycle Cost
After considering all the cost advantages — downtime avoided, low installation cost, and the minimal cost of maintenance — you’ll see how the Dynamatic® “AS” drives can be your lowest cost choice. 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.
