Product Description:
The CTP22NLF31NAA00 is produced by Kollmorgen as part of the CT Stepper Motors series. It belongs to the Cool Torque Performance Series, which focuses on higher torque density within a NEMA 23 footprint. In automated indexers, pick-and-place heads, and compact gantries, the motor converts pulse commands from a step drive into discrete shaft movement for open-loop positioning. This layout suits applications that need repeatable incremental motion without integrated optical feedback.
This unit provides a holding torque of 360 oz-in (2.54 Nm), which helps the shaft remain stable when the drive is energized at standstill. The winding is rated for 3.1 A DC, and a phase resistance of 1.31 ohms sets the electrical load seen by the drive. An applied voltage of 4.0 VDC keeps operation within low-voltage drive ranges, while winding inductance of 6.1 mH affects how quickly current rises after each command pulse. The motor also uses four lead connections and a leads-style cable exit, which keeps wiring straightforward for standard stepper drive installations. A 340 VDC insulation rating supports electrical isolation within the motor assembly.
The motor uses a Size 23 frame that measures 57 mm and is built in a 2-stack length, giving a compact format with practical torque output. Its round smooth shaft can accept axial loads up to 50 lbs (23 kg) in either direction, and the bearing system also supports radial loading at the shaft center line for common coupling and belt arrangements. Each full step moves the rotor by 1.8°, which is standard for precise incremental positioning in stepper systems. The motor has a thermal resistance of 2.62 °C/W, supporting continuous duty when heat is managed through the frame. With no rear add-ons installed, the back of the motor remains open for encoder attachment if the application requires added feedback later.
