Product Description:
The CTP32NLF11KAA00 is a hybrid stepper motor manufactured by Kollmorgen within the CT Stepper Motors series. Supplied under the Cool Torque Performance designation, it is intended for precise incremental positioning in pick-and-place stations, indexing tables, and other open-loop motion axes used in industrial automation. By converting drive current into controlled rotary steps, it removes the need for feedback devices in many medium-torque applications. That arrangement suits machines that value straightforward drive control and dependable step-by-step motion without added feedback hardware.
The motor occupies a Size 34 / 8.5 cm frame, so it can replace legacy NEMA 34 devices without mechanical changes. At its rated phase current, the CTP winding delivers 7.8 N-m of holding torque, providing margin for high-inertia loads. Each phase draws 1.1 A, which helps limit drive heating while still energizing the laminated core. Insulation is rated to 340 VDC, allowing safe operation on microstepping drives that switch high bus voltages for improved slew rates. The rotor end is machined with a straight keyway shaft, and the axial bearings tolerate 100 lbs of load in either direction, enabling direct coupling to lead screws or belt pulleys without auxiliary thrust bearings. This current level also helps keep thermal load manageable in tightly packed equipment.
Mechanical installation is simplified by the NEMA through holes mounting pattern and the two-stack lamination length, which increases torque without enlarging the motor face. Radial bearing capacity is limited to 65 lbs at the shaft center, helping protect the assembly when side loads from pulleys are present. Electrical hookup uses flexible leads with four conductors because the winding is bipolar, allowing series or parallel drive options. There are no rear-mounted encoders or brakes, which helps keep the overall length short. The leaded connection style also simplifies routing in compact machine sections where connector depth can become a constraint.
