Product Description:

The CTP22NLS19NAA00 is a hybrid stepper motor built by Kollmorgen for the CT Stepper Motors series and is part of the Cool Torque Performance lineup. Its hybrid stepper design supports repeatable indexing in compact automation axes where accurate incremental motion is required. The unit occupies a Size 23 (5.7 cm) frame and uses a 2-stack lamination to increase rotor flux. A 6.35 mm round smooth shaft transmits motion, while NEMA through-hole mounts secure the front face to machinery. Installation is simplified by six flying leads and an open rear configuration, making the motor suitable for precise open-loop positioning on pick-and-place tables, small conveyors, or metering pumps.

Electrically, the CTP variant supplies 2.54 N-m of holding torque when driven in bipolar mode and draws 1.9 A per phase. The copper network presents 3.39 ohms of resistance and 8.3 mH of inductance, which influence the voltage constant and current decay during microstepping. With a geometric step angle of 1.8°, the motor advances in 200 full steps per revolution, and inherent step accuracy remains within ±3%. Coil insulation withstands 340 VDC and maintains at least 100 megohms to ground, while a thermal resistance of 2.62 °C/W helps support continuous service without excessive winding temperature rise.

Mechanical loading allows up to 50 lbs (23 kg) of axial force in either direction and 20 lbs (9 kg) of radial force measured at the shaft center. The rotor’s reflected inertia is 0.000048 kg-m², which helps moderate start-stop transients while keeping resonance manageable. Overall body length is 83.74 mm, and the motor weighs 1.09 kg, so its mass and envelope remain compatible with compact stages. The smooth shaft works with couplings that do not require keyways, and the six-lead configuration allows series or parallel winding connections when the motor is used with chopper drives.
