AT-250204-0145
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.
Description
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.
