Product Description:

The CTP22NLS12NAA00 is a hybrid stepper motor from Kollmorgen's CT Stepper Motors series and belongs to the Cool Torque Performance line within the High Torque Performance Series. It fits the Size 23 envelope, which measures 5.7 cm, and it uses a 2-stack lamination to increase torque density without enlarging the housing. A round smooth shaft projects 20.57 mm from the front, while the rear configuration is omitted so the back face remains clear for wiring. This motor converts pulse commands into incremental rotation for indexers, pick-and-place axes, and light conveyor systems.

Motion is produced in 200 full steps per revolution, and each step measures 1.8° with a step accuracy band of plus or minus 3%. Each phase draws 1.2 A, and the windings have a resistance of 8.26 ohms and an inductance of 20 mH, which affect current rise time and microstepping smoothness. When energized, the rotor provides a static holding torque of 2.01 N-m, and the bipolar drive value listed for this model is 2.54 N-m. Six color-coded lead wires provide the electrical connection, allowing series or parallel coil hookup. The insulation system withstands 340 VDC and has an impedance of 100 megohms, which helps limit leakage current in grounded or floating supply arrangements.

For a motor in this frame size, the mechanical load capability is substantial. It can tolerate an axial thrust of 50 lbs, or 23 kg, in either direction and a radial side load of 20 lbs, or 9 kg, at the shaft center. The output shaft has a diameter of 6.35 mm, which suits clamp-style couplings and timing-belt pulleys that rely on friction instead of keys. Four NEMA through-hole bosses simplify mounting to steel or extruded aluminum plates while maintaining the 5.7 cm square pattern. The leads exit through a molded grommet, and because no connector is fitted, the conductors can be landed directly in the drive terminal strip.
