Product Description:

The CTP32NLF73KAA00 is a stepper motor manufactured by Kollmorgen in the CT Stepper Motors series. Supplied with lead wires and NEMA through-hole mounting, it fits quickly onto standard panels and couples directly to gearboxes or pulleys. Within automated packaging lines, material handlers, and small gantry stages, the model turns pulse commands from a drive into incremental rotation, providing repeatable open-loop positioning without feedback hardware.

It has a Size 34 / 8.5 cm frame that matches NEMA 34 flanges and provides adequate shaft height for mid-range belt drives. Under bipolar excitation, the CTP variant develops 7.8 N-m of holding torque, enabling direct drive of moderate inertia loads without reduction gearsets. To achieve that torque, each phase is rated for 7.3 A DC in continuous duty. Electrical losses are limited by a 0.41 Ω phase resistance, while a 3.4 mH phase inductance shapes current rise and allows smooth microstepping at typical 24 to 75 V bus levels. The rotor advances in 1.8° increments, so fine positioning can be obtained through fractional microstep commands from the controller.

With 200 full steps per revolution, the motor presents a base resolution that aligns mathematically with common drive subdivision ratios and simplifies motion calculations in PLC code. The straight keyway shaft tolerates an axial load of 100 lbs in either direction and a radial load of 65 lbs at the shaft center, permitting rigid coupling to pinions or pulleys without auxiliary bearings. A rotor inertia of 0.0370 oz-in-s² balances quick acceleration against settling stability, and the 3.0 kg mass supports predictable thermal behavior when combined with a 1.55 °C/W housing resistance. Step accuracy remains within ±3%, and a 340 VDC insulation rating safeguards the windings when higher supply voltages are used for increased slew rates.
