Product Description:

The CTP22NLF19NAA00 is a two-phase stepper motor manufactured by Kollmorgen as part of the CT Stepper Motors series, which the company also markets as the Cool Torque Performance line. This motor converts discrete current pulses from an indexer or drive into precise angular movement, making it suitable for industrial automation tasks that require incremental positioning. Its NEMA 23 frame, round smooth shaft, and through-hole mounting pattern let it fit standard motion platforms without additional brackets.

The motor can hold a load at standstill with 360 oz-in of torque. Each phase draws 1.9 A DC through copper windings that measure 3.25 Ω at 25 °C, while their inductance is 16 mH; these values indicate the electrical time constant and the drive voltage needed for fast current rise. Motion is generated in discrete increments because the rotor advances exactly 1.8° per full step, which is a standard resolution for size 23 devices. When the windings are energized with the rated 6.3 VDC, the motor meets its published speed-torque curves. Detent torque of 12 oz-in keeps the shaft from drifting when power is removed, and the rotor inertia of 0.0068 oz-in-s² helps moderate acceleration so overshoot is minimized. Insulation is designed for 340 VDC and 100 MΩ resistance, supporting dielectric strength when the drive uses high bus voltages. Thermal resistance of 2.62 °C/W helps estimate surface temperature during continuous duty.

Shaft loading is accommodated in both directions up to 50 lbs axially and 20 lbs radially at the center. This helps protect the bearings during use with pulleys or couplings. Four lead wires simplify bipolar connection to microstepping drives, and the two-stack lamination provides higher torque than single-stack models in the same footprint. With a mass of 2.4 lb, the motor adds little weight to gantry or pick-and-place axes while still achieving 3.32 N·m peak torque in CTM wiring and 2.54 N·m in the CTP configuration.
