Product Details:

KOLLMORGEN TT-29530-3145-A is a large frameless permanent magnet synchronous torque motor from Kollmorgen TT series, equipped with EnDat multi-turn absolute encoder and hollow bore structure. It adopts large-size stator and rotor stack design, delivering outstanding continuous torque and strong overload capacity, designed for long-stroke rotary and lifting axes which need to retain complete multi-turn position data after power loss. The suffix A represents standard factory sealing and bearing configuration, suitable for long-cycle continuous operation in heavy-duty storage and handling equipment.

This frameless torque motor records rotation count and rotor angle inside the EnDat multi-turn encoder. The position data will be stored without power supply. Once powered on, the matched Kollmorgen servo drive can read the full position value immediately, eliminating homing operation after restart and improving the startup efficiency of long-travel motion systems. Separate power and feedback wiring channels isolate power noise from sensitive digital signals and reduce electromagnetic interference inside high-power electrical cabinets equipped with inverters and switching components.

This variant is frameless non-brake design without integrated holding brake. Stator and rotor are supplied separately for customers to integrate directly into their mechanical frame, eliminating gearbox backlash. The large hollow bore allows cables, air pipelines and feeding materials to pass through the rotor center, which is convenient for rotary equipment with internal routing requirements. 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-time fluctuating heavy load 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 low-speed rotation and high repeat positioning accuracy for large inertia loads.

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 optimize the overall mechanical layout and reduce transmission error points. Every finished motor passes factory validation before shipment, including EnDat multi-turn memory test, low-speed torque stability test, insulation resistance inspection and vibration endurance test to guarantee stable performance in multi-shift logistics and heavy industry production lines.

It is widely deployed on automated warehouse rotary storage systems, long-travel gantry handling equipment, heavy mold rotary transfer machinery, cable winding automation and large rotary test fixtures. Typical application axes include rotary storage turntables, long-stroke gantry positioning modules, hollow rotary clamping units and angle calibration platforms. Automation integrators select this large-frame multi-turn EnDat variant for its zero-backlash direct drive, hollow through bore design and seamless compatibility with Kollmorgen motion control ecosystem.
