Product Description:

The CTP22NLF12NAA00 is a two-phase hybrid stepper motor manufactured by Kollmorgen as part of the CT Stepper Motors series, and it belongs to the Cool Torque Performance Series within that range. Its series characteristic is identified by Kollmorgen as the High Torque Performance Series, indicating elevated torque density for compact machinery. Engineered to convert pulse trains from a drive into indexed rotation, the motor is applied in pick-and-place heads, labeling systems, and other position-controlled axes that benefit from precise open-loop motion.

Rated at 1.2 A DC per phase, the windings present 8.4 Ω of resistance and 41 mH of inductance, values matched to low-current microstepping amplifiers. The two-phase construction works with a 1.8° full-step angle to deliver 200 discrete steps per revolution, while detent torque is limited to 0.08 N-m for minimal cogging when unpowered. Insulation withstands up to 340 VDC, allowing operation on shared DC buses. Under bipolar excitation the CTP designation produces 2.54 N-m of holding torque, supporting demanding stall loads without lengthening the frame. A thermal resistance of 2.62 °C/W describes heat transfer from the stator to ambient and guides drive current derating when airflow is restricted.

The mechanical assembly supports an axial load of 50 lbs (23 kg) in either thrust direction and a radial load of 20 lbs (9 kg) at the shaft center. A rotor inertia of 0.000048 kg·m² balances quick acceleration with speed stability, while the round, smooth shaft measures 6.35 mm in diameter for direct coupling. The motor occupies a Size 23 (5.7 cm) frame, uses NEMA through-hole mounting, and is built in a 2-stack length to raise torque without increasing width. Electrical terminations are four color-coded leads, no rear option is installed, and the design maintains shaft temperatures within ratings when radial fans or natural convection are present.
