Product Description:

The CTM33NLS23KAA00 is a stepper motor manufactured by Kollmorgen and supplied in the CT Stepper Motors series. As a hybrid two-phase actuator, it converts electrical pulses into fixed angular steps, allowing PLCs and indexing drives to position loads without feedback hardware. It belongs to the Cool Torque Maximum family and is suited for pick-and-place arms, small conveyors, and automated inspection fixtures where repeatable holding torque and basic speed control are sufficient. Because step position is created by commanded pulse counts, the motor is often used in systems that prioritize repeatable indexing over closed-loop servo correction.

This motor uses a Size 34 frame with an 8.5 cm square face, matching the common NEMA 34 mounting footprint. A mechanical stack length of 3-stack laminations increases the magnetic path and raises output capability. Under bipolar excitation, the rotor can deliver up to 13.6 N-m of torque. Each phase draws 2.3 A of winding current, so many mid-range stepper drives can power the unit without oversizing. The insulation system is rated for 340 VDC, allowing the windings to withstand higher DC bus voltages used in modern microstepping amplifiers while maintaining thermal margin.

The shaft can accept an axial load of 100 lbs in either direction and a radial load of 65 lbs at the centerline, supporting pulley or leadscrew mounting without additional outboard bearings. Electrical termination is through six color-coded leads arranged in a unipolar pattern, which allows series or parallel wiring. The lead arrangement also supports common stepper drive connection schemes without requiring a separate feedback cable. For mechanical attachment, the housing provides NEMA through holes, so the motor can bolt directly to standard faceplates. A straight keyway shaft simplifies coupling design, and the absence of rear accessories leaves clearance for tight cabinet layouts.
