Product Description:
The CTM22NLF06NAA00 is a 2-phase stepper motor produced by Kollmorgen within the CT Stepper Motors series and aligned with the Cool Torque Maximum designation. Intended for open-loop or indexer-driven axes, the unit converts electrical pulse trains into incremental rotary motion for positioning tasks in industrial automation, where repeatable movement is often required without a separate feedback device. The size 23 frame and NEMA through-hole mounting allow direct integration with linear slides or small conveyors. Its round smooth shaft supports coupling to timing pulleys or lead screws for precise, low-backlash transfer of torque in compact motion assemblies.
Each full revolution is divided into 200 discrete steps, produced by a mechanical step angle of 1.8°. The windings draw a rated phase current of 0.60 A DC through four lead connections, and they present a typical resistance of 32.2 Ohms and an inductance of 108 mH. Together, these values influence current rise and damping behavior, so the drive can be matched to the motor's electrical response during acceleration and settling. Step accuracy is ±3%, and insulation is rated to 340 VDC with 100 megohms of resistance, which supports reliable operation on standard microstepping drives. This combination helps the motor deliver consistent incremental motion in applications that depend on stable low-speed positioning.
Mechanical performance is led by a bipolar holding torque of 3.32 N-m and shaft load limits of 50 lbs axially and 20 lbs radially at the shaft center. The 2 Stack rotor arrangement generates this torque while limiting inertia to 0.0068 oz-in-s², which supports fast start-stop duty and helps the motor respond cleanly to rapid indexing commands. A thermal resistance of 2.62 °C/W supports heat-rise analysis under continuous current, and the rear of the housing is supplied without additional devices to simplify routing in tight spaces. This layout is well suited for compact machines where available space is limited and unobstructed cable exit is important.
