Models AT-140 Through AT-440 “AT” Drives 1 through 200 HP
■Dynamatic Model AT Drives is a combination of an air-cooled, adjustable speed clutch and a flange mounted AC induction motor. The AT Drive transmits torque at variable speeds. There is no physical contact between input and output members. This results in smooth response, thereby eliminating shock loading and extending equipment life. All drives have an integral tachometer generator mounted around the output shaft to provide a feedback signal to the drive's controller. The controller provides the DC excitation for the clutch coil. The feedback signal from the tachometer generator is used as a reference signal within the controller to maintain accurate speed regulation.
●Features & Benefits
■AC power input – AT drives and controllers are available to run on virtual any 3-phase voltage input, which makes them compatible with existing wiring and plant power.
■Approximately 250% motor torque available at clutch output. Accelerates high inertia loads quickly and handles intermittent overloads without having to increase the horsepower rating.
■AT drives are built to give long, reliable, low-cost life in diverse applications, including harsh environments.
■Simple design – Drive consists of a clutch, AC induction motor and separate controller. This makes them easy to understand, install, operate and maintain.
■Fewer wearing parts – All AT variable speed drives have only four bearings an no slip rings or brushes. This prevents downtime and allows maximum production from initial startup.
■0.5% speed regulation is standard. Provides a consistent, high quality product under changing load and environmental conditions.
■Uses existing wiring and motor starters. Easy to retrofit in industrial environments.
■Totally enclosed fan-cooled AC motor is standard, which makes it suitable for harsh environments.
