Product Description:

The CTM33NLS37KAA00 is a hybrid stepper motor manufactured by Kollmorgen for the CT Stepper Motors series. It also carries the Cool Torque Maximum Series designation, which indicates a design intended to deliver high torque with good efficiency. In automated machinery, it converts pulse commands from an indexer or PLC into precise incremental motion for packaging lines, small machine tools, and pick-and-place stages. A 3-stack stator increases magnetic path length and raises torque density without increasing the frame size.

Electrical performance centers on a continuous phase current of 3.7 A, and this value governs drive selection and resistive heating. At that current, the CTM winding delivers a holding torque of 13.6 N·m, giving the motor strong static torque for indexing and positioning tasks. The insulation system is rated for 340 VDC, permitting use with high-bus microstepping controllers without overstressing the winding. A square Size 34 frame with an 8.5 cm flange matches the common NEMA 34 footprint for straightforward mounting. Electrical flexibility is provided by six connections brought out as color-coded leads, allowing series or parallel bipolar drive arrangements to suit current and inductance requirements.

Mechanical loading capacity includes axial thrusts of 100 lbs in either direction and radial forces of 65 lbs at the shaft center, so the motor can support belt tension or moderate pinion overhang without added external support. Face mounting uses NEMA through holes, which simplifies installation on standard machine frames and adapter plates. The output shaft uses a straight keyway, helping resist slip during repeated starts, stops, and reversals. No rear accessory is installed, so space remains open for optional encoder or brake additions and the wiring exit remains unobstructed.
