Product Details:

KOLLMORGEN TT2953-4011-B is a medium-frame direct drive permanent magnet synchronous servo motor from Kollmorgen TT series, equipped with incremental commutation feedback and keyway shaft. It adopts optimized stator stack and winding design, delivering balanced continuous torque and good overload capacity, tuned for medium-speed continuous operation on web converting and packaging machinery. The suffix B stands for customized bearing preload and sealing option, suitable for workshop environments with fine dust and coolant splashing.

This servo motor transmits differential incremental pulse and commutation signals to matched Kollmorgen servo drives for closed-loop speed and tension control. It maintains stable speed ratio for multi-roller synchronization, and homing procedure is required after each power cycle to establish position reference. Separated power and feedback wiring paths reduce electromagnetic noise interference inside industrial electrical cabinets with inverters and switching modules.

This variant is non-brake design without integrated holding brake, suitable for 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 damage during long-cycle continuous production. 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 minimizing tension fluctuation for thin film and flexible 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 flexible film winding equipment, label processing lines, packaging rotary transfer machines, calender auxiliary rollers and electronic assembly positioning stations. Typical application axes include tension control rollers, rotary positioning turntables, web guiding modules and medium-speed reciprocating positioning units. Automation integrators select this TT series direct drive variant for its smooth medium-speed running, consistent tension performance and seamless compatibility with Kollmorgen motion control ecosystem.
