Product Description:
The CTM31NLS22KAA00 is a hybrid stepper motor manufactured by Kollmorgen and placed in the CT Stepper Motors series within the Cool Torque Maximum family. Built for indexing tables, precision feeders, and other incremental motion tasks, the unit converts pulse commands from a drive into controlled rotary steps without an internal feedback device. The Cool Torque Maximum designation marks models that deliver higher static torque from a compact envelope, allowing higher force density while retaining standard NEMA mounting dimensions. Because it operates as a stepper motor, motion is produced in discrete angular increments that suit repeatable positioning tasks.
The motor occupies a Size 34 frame that measures roughly 85 mm across the mounting face, allowing it to fit standard NEMA 34 mounting patterns. A holding capability of 4.9 N-m is produced with a phase winding limited to 2.2 A, so the motor can provide high stall torque while keeping drive current moderate. Class B insulation rated for 340 VDC supports operation on modern micro-stepping drives that raise bus voltage for improved high-speed torque. Electrical hookup is through six leads, permitting series or parallel bipolar connection schemes, and the leads exit as a potted cable that simplifies routing on moving carriages. That wiring flexibility lets the motor be matched to different drive voltage and current ranges without changing the basic frame. A single-stack lamination length further reduces motor depth for tight equipment layouts.
The straight shaft accepts up to 100 lbs of axial force in either thrust direction and withstands 65 lbs of radial load at the centerline, so pulleys or gears can be mounted without extra support bearings. The straight shaft layout suits couplings, gears, and timing pulleys used on compact indexing axes. Attachment is through NEMA Through Holes, allowing the housing to bolt directly to a flange or plate. Torque is transferred by a Straight Keyway, which helps prevent slip during repetitive indexing. The motor has no rear attachments, and the air gap is optimized for maximum torque and efficiency.
