These Eddy Current 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 adjustable speed drives. In fact, they are about as easy to install as electrical motors.
Controllers for Dynamatic® AT drives use only 1% 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 your press.
Simple, rugged design
Look inside a Dynamatic® AT drive and you’ll see why it’s the leader in adjustable speed drives. Nothing is simpler yet offers such high performance and proven reliability.
Since torque is transmitted through an electromagnetic coupling there is no wear as occurs with drives utilizing 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 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! And the TEFC motor allows for outdoor operation.
These adjustable speed drives have their own internal cooling fans, so there is no need for external cooling systems that can fail.
Dynamatic® AT drives feature optional built-in Eddy Current brakes. Designed for controlled deceleration of the drive through the stroke or when stopping the flywheel, this is a big plus when stamping deep drawn material. No tearing of the metal means less scrap and more parts, faster!
