Product Description:
The CTP31NLS56KAA00 is a hybrid stepper motor produced by Kollmorgen within the CT Stepper Motors series. As a positioning element, the motor converts discrete pulse commands from a stepper drive into incremental shaft movement for automated indexers, pick-and-place heads, and light machining axes. Its single-stack construction belongs to Kollmorgen’s Cool Torque Performance family, which emphasizes high torque density at moderate frame sizes for factory equipment that requires accurate incremental motion.
Rated bipolar torque reaches 4.0 N-m when the windings carry the specified phase current of 5.6 A. The square lamination measures Size 34 / 8.5 cm, which matches common gearbox flanges and couplings used with this motor class. An insulation system verified to withstand 340 VDC allows the coils to be driven by higher-voltage micro-stepping amplifiers that improve low-speed smoothness. Electrical termination is through six color-coded leads, permitting either series or parallel connection of the two phase windings to match supply voltage and the required torque-speed profile.
Mechanical loading is accommodated by an axial shaft limit of 100 lbs in either thrust direction and a radial allowance of 65 lbs at the shaft center, which helps protect bearing life under normal installation loads. Mounting to the machine frame uses NEMA through holes, providing direct interchange with other NEMA 34 stepper motors and eliminating the need for adapter plates in many installations. Power is transmitted through a shaft with a straight keyway, which provides positive torque transfer to pulleys or couplings without relying only on friction fits. The mounting pattern and keyed shaft support straightforward integration into motion stages and other compact rotary assemblies.
