Dynamatic® AT Drives
Rugged, Reliable Performance Through . . .
|
Flexible, Precise Control
Available in 1 through 200 HP, the Dynamatic® “AT” adjustable speed drives with tachometer feedback let you control speed within 1/2 percent from no load to full load. You also get 250 percent of rated torque – great for starting and momentary overload conditions. Compared with other drives offering only 110 percent to 150 percent torque, a smaller drive can often be used.
A Two Year Warranty
We take our commitment to high quality seriously at Dynamatic® and it shows in the long life cycle our customers have come to expect from the Dynamatic® line. It also shows in our 2 year warranty.
We also load test every controller and drive 100 percent before it leaves the factory, so you can count on reliable startup and consistent performance.
Easy Installation
The Dynamatic® “AT” 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 don’t need highly trained personnel to install these drives. In fact, they are about as easy to install as electrical motors.
Controllers for Dynamatic® “AT” drives use only 1 percent of line power, so 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 Dynamatic® “AT” drives in a vertical position without expensive modifications.
No Power Line Pollution
Since there are no fast switching devices, the controllers meet FCC Part 15, Class A and B. They also meet the requirements of ANSI / IEEE 519 without the use of line fillers, capacitors and chokes.
Simple, Rugged Design
A look inside the Dynamatic® “AT” drive tells you why it’s the leader in adjustable speed drives. Nothing is simpler yet offers such high performance and reliability.
Since torque is transmitted through an electromagnetic coupling there is no wear as occurs with drives which utilize friction material or belts to transmit torque. No slip rings or brushes to replace or clean, just four bearings ensure more uptime, and minimal maintenance... all of which are advantages manufacturers find especially important.
A cast iron housing, brushless clutch coil, and solid-state controllers, are ideal features for harsh conditions – oil, dirt, dust, high humidity and more!
Additionally, the TEFC motor allows for outdoor operation.
These drives have their own internal cooling fans, so there is no need for external cooling systems that can fail.
A Small, Simple Controller and PLC Compatibility
The entire solid-state controller consists of one printed circuit board, and it’s interchangeable among a wide range of drive horsepowers to reduce your inventory and save money.
Dynamatic® offers a full range of digital controls with many standard features for optimal performance.
Interfacing the Dynamatic® “AT” drive to computer control systems is a snap. The controller interfaces easily with PLC systems.
And Don’t Forget About Economy
After considering all the cost advantages – downtime avoided, low installation cost, and the minimal cost of maintenance – you’ll see how the Dynamatic® “AT” drive can be your lowest cost choice.
When used within the normal operating range on fans and pumps, their energy efficiency is equal to or better than other types of drives.
