Product Description:

The CTP32NLF99KAA00 is a hybrid stepper motor produced by Kollmorgen for the CT Stepper Motors series and cataloged under the Cool Torque Performance Series. It fits a Size 34, 8.5 cm frame and uses a 2-stack lamination to raise flux density without extending the housing. The motor has a straight keyway shaft and uses NEMA through-hole mounting, while four color-coded leads supply phase power. No rear accessories are fitted. This configuration provides accurate incremental motion for automated indexers and feed systems that do not require closed-loop feedback.

The motor delivers up to 7.8 N·m holding torque when driven at 9.9 A DC per phase, which aligns with its High Torque Performance Series designation. A step angle of 1.8° generates 200 full steps per revolution, and mechanical deviation stays within ±3% for repeatable positioning. Detent torque of 0.21 N·m limits unwanted drift when power is removed. The shaft tolerates 100 lb (45 kg) axial load in either direction and 65 lb (29 kg) radial load at the center, so couplings, gears, or pulleys may be mounted without additional support. The frame mass is 3.0 kg, which helps keep moving inertia manageable on gantry axes.

Electrically, each phase presents 1.8 mH inductance and 0.23 Ω resistance, permitting rapid current changes from a low-voltage micro-stepping drive while keeping copper loss manageable. Thermal resistance of 1.55 °C/W relates winding temperature rise to case dissipation, and a rotor inertia of 2.61 kg·cm² helps balance dynamic response with load requirements. The insulation system withstands 340 V DC and offers 100 MΩ resistance for use in noisy plant environments. Straight leads simplify routing through cable tracks, and the absence of rear components shortens the overall length for compact machine frames.
