Product Description:

The CTP22NLF50NAA00 is a hybrid stepper motor manufactured by Kollmorgen for the CT Stepper Motors series and positioned in the Cool Torque Performance range. It converts commanded phase currents into fixed angular movement for open-loop positioning in automated feeders, test fixtures, and compact gantries where servo feedback is not required. A two-stack rotor supports consistent incremental motion, and the NEMA through-hole mounting pattern helps the motor fit common machine layouts. Because it operates as an open-loop device, it is well suited for indexing tasks that need repeatable positioning without closed-loop correction hardware.

The winding pair draws up to 5.0 A, which sets the drive output requirement and the heat that must be removed by natural convection. The electrical values include a phase resistance of 0.52 ohms and a phase inductance of 2.2 mH, which influence current rise during stepping and microstepping operation. In bipolar mode, the motor produces 2.54 N·m of holding torque to resist motion when the shaft is energized at standstill. Each revolution contains 200 full steps, and the resulting 1.8 degrees per step works with standard pulse tables for predictable indexing and smooth commanded movement.

A housing length of 3.297 in keeps the motor compact while still accommodating the two-stack magnetic circuit. The assembly weighs 2.4 lb, which helps limit the load added to slides, brackets, and belt-driven axes in compact machines. The bearings can support 50 lb of axial thrust in either direction, allowing the round smooth shaft to handle light lead-screw preload or coupler force. The shaft center radial load capacity is 23 kg, insulation resistance is 100 megohms, and the dielectric rating is 340 VDC. These values fit common indexers and PLC-controlled motion modules used in industrial automation.
