Product Description:

The CTP22NLS49NAA00 is a two-stack stepper motor produced by Kollmorgen within the CT Stepper Motors series. It belongs to the Cool Torque Performance Series and offers high torque performance, so it provides elevated torque density for motion axes that need incremental positioning without closed-loop feedback. In an automation cell, it translates step and direction pulses from an indexer or micro-stepping drive into fixed angular moves, making it suitable for conveyors, small gantries, or metering pumps that depend on repetitive, accurate rotation.

Electrically, the motor draws 4.9 A per phase at rated load. A phase resistance of 0.53 Ω limits I²R heating, and the compact windings exhibit 1.2 mH inductance, allowing high slew rates when paired with a current-mode driver. Rotor position advances in 200 full steps per revolution, with each step spanning 1.8°, which is standard for size-23 devices. Six welded leads provide bipolar or unipolar connection options, and no rear accessories are fitted, so cable routing is direct. The square frame measures 5.7 cm and mounts with NEMA through holes, while the round smooth shaft fits couplings without key machining. Insulation withstands 340 VDC and has an insulation resistance of 100 MΩ. Rotor inertia of 0.000048 kg·m² and a thermal resistance of 2.62 °C/W support responsive motion and continuous duty within the aluminum housing.

The motor weighs 1.09 kg and delivers a continuous bipolar torque of 2.54 N·m, allowing direct drive of lead screws or timing belts. The bearings accept an axial thrust of 50 lb (23 kg) in either direction and a radial load of 20 lb (9 kg) at the shaft center without exceeding bearing limits. These load capacities help reduce misalignment stress and maintain step accuracy under changing side forces in indexing tables and small actuators.
