Product Description:

The CTP20NLF17NAA00 is a hybrid stepper motor produced by Kollmorgen within the CT Stepper Motors series. Within the Cool Torque Performance Series, this model offers high torque performance and fits NEMA-23 mounting envelopes used on pick-and-place actuators, indexing tables, and similar motion axes. As a two-phase device, it converts discrete drive pulses into accurate angular positions, providing open-loop motion control in industrial automation equipment.

For electrical operation, each phase draws 1.7 A DC, and each winding has 2.87 Ω of resistance with an inductance of 7.1 mH. These values affect the driver voltage requirement and the motor's current rise time. When energized, the short-stack rotor can deliver a holding torque of 0.71 N·m, while intrinsic detent torque is limited to 0.04 N·m for smooth microstepping. Position resolution comes from the 1.8° step angle, and dynamic response benefits from the low rotor inertia of 0.000018 kg·m². The motor has a size 23 frame, a 40.7 mm body length, and NEMA through-hole mounting. A four-lead connection style simplifies wiring, and a thermal resistance of 3.99 °C/W assists heat flow to the mounting surface.

The motor supports an axial load of 50 lbs (23 kg) in either thrust direction and a radial load of 20 lbs (9 kg) at the shaft center, which helps protect bearing life in belt-driven systems. The smooth, round shaft measures 6.35 mm in diameter and exits the front only. There is no rear shaft, which supports compact enclosure layouts. Overall mass is 0.45 kg, easing installation on lightweight gantries. Electrical insulation withstands 340 VDC, supporting reliable isolation within the winding system. The mounting pattern helps maintain alignment under vibration, while the aluminum frame aids heat dissipation from the windings.

Internal Product Review

  • ‘‘The CTP20NLF17NAA00 is a Kollmorgen CT stepper motor that delivers 0.71 N·m bipolar torque with a 1.8° step angle for accurate indexing. Short-stack construction and NEMA through-hole mounting make integration especially clean in compact motion assemblies. A 1.7 A DC rated current paired with 7.1 mH phase inductance gives this motor a very capable balance of control and torque.’’
