Product Description:

The CTP22NLS31NAA00 is a hybrid stepper motor engineered by Kollmorgen for the CT Stepper Motors series and cataloged under the Cool Torque Performance Series. Built on a Size 23 (57 mm) frame, the unit converts discrete control pulses into precise rotary motion for indexing tables, pick-and-place heads, and other position-dependent automation stages that do not require closed-loop feedback. Its hybrid design supports repeatable incremental movement in compact machines where stable step positioning is more important than servo feedback.

The motor supplies a holding torque of 2.01 N-m, enough to maintain position when idle without an external brake. Electrical drive current reaches 3.1 A DC per phase, and the phase resistance is 1.30 ohms with a phase inductance of 3.0 mH. Coil insulation is rated to 340 VDC, supporting operation on high bus voltages while meeting Class B temperature limits aided by a 2.62 °C/W thermal resistance. The motor executes 200 full steps per revolution, which corresponds to a 1.8° step angle, and its six leads allow series or parallel bipolar wiring to match different power supplies. A through-hole NEMA mounting face simplifies direct mating to gearheads, and all wiring exits as permanently attached leads from the front endbell.

The rotor tolerates an axial shaft load of 50 lbs in either direction and a radial load of 20 lbs at the shaft center, allowing belt tension or end-thrust coupling without premature bearing wear. Dynamic response benefits from a low rotor inertia of 0.000048 kg-m², and the 2-stack lamination design supports higher torque density. Overall dimensions are 83.74 mm in length and 57.15 mm in body width. The round smooth shaft measures 6.35 mm in diameter and 20.57 mm in usable length. With a mass of 1.09 kg and no rear accessory, the motor remains compact for direct installation, and the shaft proportions suit couplings, pulleys, and similar drive elements used on light and medium-duty positioning axes.
