Product Details:

KOLLMORGEN TT-2952-4051-A is a medium-frame direct drive permanent magnet synchronous servo motor from Kollmorgen TT series, equipped with incremental commutation feedback and keyway shaft. It is rated for 3000 rpm and optimized for medium inertia rotary and tension control axes that demand fast speed response and consistent torque stability during continuous cyclic operation. The suffix A stands for standard factory winding and bearing configuration, designed for long-run converting machinery with moderate shock load.

This servo motor transmits differential incremental pulse and commutation signals to matched Kollmorgen servo drives for closed-loop speed and tension regulation. It delivers stable speed following performance for multi-roller synchronization, and homing procedure is required after each power cycle to establish position reference. Separate power and feedback wiring paths isolate electrical noise from sensitive pulse signals, improving signal stability in industrial cabinets with inverters.

This variant is non-brake design without integrated holding brake, suitable for horizontal unwinding and rewinding rollers, packaging rotary feed axes and medium-speed positioning platforms where static locking is handled by external mechanical brake. The keyway shaft provides reliable torque transmission with gearboxes and reducers and prevents slippage under fluctuating tension load. The stator winding uses Class F insulation material and integrates PTC thermal sensor for real-time winding temperature monitoring to avoid overheating during long-time continuous operation. The motor housing reaches IP54 protection grade to resist workshop dust and incidental liquid splashing. Optimized low cogging magnetic circuit suppresses torque ripple greatly, maintaining steady rotation speed and reducing tension fluctuation for web materials.

It supports torque control, speed control and position control modes, and all motion parameters can be tuned conveniently via Kollmorgen WorkBench software. Direct drive structure eliminates gear backlash and reduces routine maintenance points. Every finished motor passes factory validation before shipment, including incremental encoder calibration, speed stability test, insulation resistance inspection and vibration endurance test to guarantee stable performance in multi-shift converting and packaging production lines.

It is widely deployed on film winding equipment, packaging rotary transfer lines, label processing machines, calender auxiliary rollers and electronic assembly positioning stations. Typical application axes include tension control rollers, rotary positioning turntables, web feed driving modules and medium-speed reciprocating positioning units. Automation integrators select this TT series direct drive variant for its smooth high-speed running, reliable tension performance and seamless compatibility with Kollmorgen motion control ecosystem.
