Product Description:

The CTP22NLF06NAA00 is a hybrid stepper motor built by Kollmorgen for positioning and incremental feed duties in industrial automation. It belongs to the CT Stepper Motors series and carries the Cool Torque Performance Series designation within that range. It is intended for high-torque performance in compact motion systems. By delivering precise 1.8-degree incremental motion while accepting digital pulse commands, the motor converts electrical control signals into repeatable rotational steps for index tables, gantries, and compact actuators.

This model has a 3.297 in (83.74 mm) body, a Size 23 frame with standard NEMA through-holes, and a 0.2500 in smooth round shaft driven by a two-stack rotor. The shaft tolerates an axial force of 50 lb (23 kg) in either direction and a radial load of 20 lb at the shaft center, allowing belt tensioning or light gear coupling without additional bearings. Under bipolar excitation, the CTP winding develops 2.54 N-m of holding torque while drawing a rated phase current of 0.60 A across a phase resistance of 32.2 Ω. Four lead connections provide the full-coil layout, and the 340 VDC insulation rating separates the copper from the laminated core for high-voltage drive topologies.

The electromagnetic properties are shaped by a coil inductance of 150 mH, so the drive must supply adequate voltage when slewing at the 200 full steps per revolution that correspond to a 1.8° step angle. Rotor inertia is 0.0068 oz-in-s², enabling quick index moves without excessive settling time, and the two-stack construction helps sustain that inertia value while increasing torque density. The motor weighs 2.4 lb (1.09 kg), which helps reduce load on linear axes, and its thermal path yields a case-to-ambient resistance of 2.62 °C/W when forced convection is not used. No rear add-ons are fitted, lead wires exit directly, and the smooth shaft simplifies coupling in high-torque applications.
