Product Description:

The CTP33NLS23KAA00 is a hybrid stepper motor produced by Kollmorgen within the CT Stepper Motors series. As a closed-loop-ready actuator, it converts discrete drive pulses into precise angular motion for positioning tables, feeders, and incremental indexing tasks common in industrial automation. The motor’s 34-frame envelope, multi-stack lamination design, and through-hole NEMA mounting simplify interchange with existing equipment while maintaining the manufacturer’s Cool Torque Performance features that emphasize high static torque output.

The mechanical package follows a Size 34 frame standard that sets the 8.5 cm square mounting pattern and supports the 128.09 mm body length. Static load retention is handled by a holding torque of 8.39 N·m, allowing the shaft to resist process forces whenever the coils are energized but motionless. Each phase carries a rated current of 2.3 A, so the drive amplifier must supply that value to reach nameplate performance without overheating. Coil inductance is 21 mH, so current rise time is moderate and helps micro-stepping smoothness at low speeds. A per-phase resistance of 4.31 Ω influences the voltage required for full current and affects thermal dissipation during dwell periods.

Motion granularity is fixed at a 1.8° step angle, yielding 200 full-step positions per revolution and enabling straightforward conversion between commanded pulses and linear travel. Dynamic response is assisted by a rotor inertia of 3.92 kg·cm², which balances torque production with acceleration capability in pick-and-place axes. The shaft can tolerate up to 100 lbs of axial load and 65 lbs of radial load at the center, supporting belt tension or thrust couplings without additional bearings. Continuous service is permitted from -20 to +40 °C, while operation outside that range requires derating or enclosure conditioning. Six flying leads provide flexible bipolar or unipolar wiring, the straight-keyed 12.7 mm shaft simplifies coupling, and the 4.1 kg mass helps spread heat during extended duty cycles.
