Product Description:
The CTP31NLF99KAA00 is a hybrid stepper motor built by Kollmorgen for the CT Stepper Motors series. Within the Cool Torque Performance and High Torque Performance groupings, this motor provides incremental motion control for positioning tables, indexers, and other open-loop automation axes that do not require feedback. Its 34-frame housing fits applications that use NEMA 34 geometry, and the part’s single-stack lamination keeps overall length compact while sustaining the torque levels typical of this product line.
This motor delivers a holding torque of 4.0 N·m when driven in bipolar mode, and each phase can be energized continuously at 9.9 A DC. A 340 VDC insulation rating separates the windings from the laminated core, permitting operation on high-voltage micro-stepping drives without electrical breakdown. The frame is Size 34 / 8.5 cm, which matches the pilot diameter and mounting bolt circle used for NEMA 34 installations. Power is introduced through leadwires rather than connectors, and exactly four connections are provided to accommodate standard bipolar drive topologies. Internally, the windings follow a bipolar pattern, and the single-stack design minimizes detent torque while maintaining the thermal path needed for continuous duty.
The motor can handle an axial load of 100 lbs (45 kg) in either thrust direction and a radial load of 65 lbs (29 kg) at the shaft center, so the bearings remain within typical L10 life targets under belt or pulley tension. The output shaft uses a straight keyway to transmit torque without slippage, and the front face is drilled with NEMA through holes for direct attachment to gearboxes or mounting plates. No rear hardware is installed, so additional encoders or brakes must be added externally if required.
