Product Description:

The CTP31NLF09KAA00 is a two-phase stepper motor produced by Kollmorgen within the CT Stepper Motors series. As a Cool Torque Performance model, it converts discrete command pulses into incremental shaft movement for indexing tables, labeling heads, and other motion axes that do not require continuous feedback. In industrial automation, this motor provides repeatable positioning while remaining simple to drive because it holds position magnetically when pulses stop and does not require an encoder. This operating method makes it well suited for open-loop motion tasks where stable step response and straightforward control are more important than closed-loop correction.

Its peak holding torque for the CTP winding is 4.0 N-m, allowing direct coupling to medium-inertia loads without mechanical gear reduction. That torque is delivered while each phase draws only 0.9 A, so a low-current microstepping drive can be used and thermal rise stays moderate. The frame conforms to NEMA Size 34 dimensions with through-hole mounting, making the motor suitable for legacy bracket patterns. Internal coils are wound in a bipolar configuration, and the stator exits with four leads in black, orange, red, and yellow insulation. This lead arrangement supports common drive wiring layouts while keeping phase connections easy to identify during installation.

The straight keyway shaft accepts an axial force up to 100 lbs in either thrust direction and a radial force of 65 lbs measured at the shaft center, allowing belt tension or overhung pulley loads without excessive bearing stress. Insulation on the windings is rated for 340 VDC, giving added margin against induced voltages during rapid deceleration and switching events. A single lamination pack, identified as 1 stack, keeps rotor inertia low for quick step response while supporting the high-torque intent of the Cool Torque line. No rear add-ons are fitted, so the overall motor depth stays compact in crowded machine frames. This layout also leaves more clearance behind the motor for cable routing, couplings, and adjacent hardware.
