Product Description:

The CTP31NLF28KAA00 stepper motor is produced by Kollmorgen and belongs to the CT Stepper Motors series, which is part of the Cool Torque Performance line. As a two-phase hybrid motor, it converts pulse commands from a compatible driver into incremental shaft rotation for controlled positioning in automated machinery. It is often used in pick-and-place actuators, indexing tables, and small conveyors where repeatable open-loop motion is suitable for the task. This type of motor is well suited to applications that need accurate stepping behavior without a separate feedback device.

The motor delivers a bipolar holding torque of 4.0 N-m in the CTP variant, helping it resist shaft movement when the load is stationary. Its phase windings draw 2.8 A, so the drive must supply that current continuously to maintain rated performance. The motor uses a Size 34 / 8.5 cm frame based on NEMA 34 dimensions, which supports straightforward installation in standard machine layouts. Coil insulation is rated for 340 VDC, providing added tolerance against voltage spikes that can occur during rapid deceleration. Mechanical mounting is provided through NEMA through holes, which allows direct attachment to compatible brackets and mounting plates.

The shaft can carry up to 100 lbs (45 kg) of axial force in either direction, and it supports radial loads of up to 65 lbs (29 kg) at the centerline. A straight keyway shaft provides positive torque transfer to pulleys, couplings, or similar driven components. The rotor uses 1 stack, which keeps the motor compact while supporting the torque level of this frame size. Four lead wires exit from the integral cable for bipolar wiring, and the rear face is open without added hardware. These features make the motor practical for compact motion axes that need dependable torque, standard mounting, and direct mechanical coupling.
