Product Details:

KOLLMORGEN TT-2950-3055-R is a frameless permanent magnet synchronous torque motor from Kollmorgen TT series, equipped with ComCoder incremental commutation feedback. It adopts medium frame size and optimized winding structure to deliver stable continuous torque and sufficient overload capacity, designed for low-speed rotary test benches and continuous tension axes that pursue zero-backlash direct drive. The suffix R represents customized bearing preload and thermal matching configuration for long-duration cyclic test workloads.

This frameless torque motor outputs incremental pulse and commutation signals to matched Kollmorgen servo drives for closed-loop speed and torque regulation. It needs homing operation after power restart to establish the position reference, and the differential pulse signal ensures stable transmission under industrial electromagnetic interference environment. Separate power and feedback wiring layout reduces noise interference inside compact electrical cabinets.

This variant is frameless non-brake design without integrated holding brake. The stator and rotor are supplied separately for customers to integrate directly into their mechanical assembly, eliminating gearbox backlash. The hollow bore structure allows cables, sensors and pipelines to pass through the rotor center. The stator winding uses Class F insulation material and integrates PTC thermal sensor for real-time temperature monitoring, preventing overheating damage during long-time low-speed continuous operation. The motor components reach IP54 protection grade to resist workshop dust and minor liquid splashing. Optimized low cogging magnetic circuit suppresses torque ripple greatly, maintaining ultra-smooth rotation and consistent torque output for precision load testing.

It supports torque control, speed control and position control modes, and all motion parameters can be tuned conveniently via Kollmorgen WorkBench software. Frameless integration helps reduce the overall machine size and cut down transmission error points. Every finished motor passes factory validation before shipment, including ComCoder pulse calibration, low-speed torque stability test, insulation inspection and vibration endurance test to guarantee stable performance in multi-shift test and converting industry lines.

It is widely deployed on rotary torque test benches, material fatigue testing equipment, film winding tension stations, low-speed rotary positioning fixtures and precision rotary calibration platforms. Typical application axes include torque loading modules, rotary test turntables, tension control drums and angle adjustment units. Automation integrators select this frameless incremental torque variant for its zero-backlash direct drive, smooth low-speed torque output and seamless compatibility with Kollmorgen motion control ecosystem.
