Product Description:
The CTP32NLS58KAA00 is a hybrid stepper motor manufactured by Kollmorgen for the CT Stepper Motors series in the Cool Torque Performance family. Designed for industrial automation, it converts pulse trains into incremental motion for slides, rotary tables, and pick-and-place heads without feedback. Its NEMA 34 footprint allows it to replace legacy units while providing the higher torque density associated with this motor class. This layout is well suited to open-loop positioning tasks where repeatable step movement is required.
The motor uses a NEMA Size 34 frame, measuring 8.5 cm, with NEMA through holes for direct front-face mounting. Its two-stack construction keeps the body depth to 3.80 in, yet the rotor delivers a holding torque of 890 oz-in to maintain position under load. During motion, each 1.8° full step is produced by a 2-phase winding set that draws a rated current of 5.8 A per phase at 0.65 Ω, and the phase inductance of 2.8 mH helps keep current rise times short while staying below the 340 VDC insulation limit. Rotational response is influenced by a rotor inertia of 0.0370 oz-in-s², and axial thrust loads up to 100 lbs can be applied in either direction without exceeding bearing limits.
A detent torque of 30 oz-in helps resist drift when power is removed, and the six-lead design allows series or parallel wiring. This gives the motor flexibility when it is matched to drives with different current and speed requirements. Radial load at the shaft center is limited to 65 lbs, and the straight keyway simplifies coupling to mating components. Within the Cool Torque Performance family, the motor produces 9.5 N-m of bipolar torque in CTM wiring or 7.8 N-m in the CTP connection when supplied with 3.7 VDC. A thermal resistance of 1.55 °C/W helps control temperature rise, the rear configuration has no added hardware, and the overall mass is 6.5 lb.
