CTM31NLF09KAA00

The Kollmorgen CTM31NLF09KAA00 step motor, part of the CT Stepper Motors series, delivers high-performance motion control in a NEMA 34 frame. Manufactured by Kollmorgen, this CTM31NLF09KAA00 unit integrates advanced magnetic design and a compact footprint to optimize system efficiency. Its enhanced rotor assembly supplies concentrated torque while maintaining energy consumption at just 75% of standard levels. The motor’s rugged packaging accommodates demanding industrial environments without compromising precision. With its proven durability and efficient design, the CTM31NLF09KAA00 addresses a broad range of automation requirements.

The CTM31NLF09KAA00 sports a Current Amps DC: 0.9 A rating and an Inductance: 112 mH that supports stable current delivery during microstepping. Its Resistance: 19.5 Ω ±10% ensures predictable thermal behavior when combined with a Thermal Resistance: (Mounted °C/Watt) 2.02. The motor’s Net Weight: 4.1 lbs and NEMA size 34 (8.5 cm) frame facilitate straightforward mechanical integration. Equipped with two windings, the unit exhibits a step angle: 1.8° (200 steps/rev) and maintains step accuracy: ±3% across its operating range. Classified under Insulation Class B (max 130°C), this motor supports reliable performance at elevated temperatures.

Operational performance derives from Kollmorgen’s proprietary SIGMAX magnetics, which boost torque density by channeling flux directly between stator teeth. The CTM31NLF09KAA00 generates a holding torque span of 3.9 to 13.6 N·m, adapting to both light-duty indexing and heavy-load applications. Leaded connection style and NEMA through-hole mounting simplify installation in multi-axis gantry systems or rotary indexing platforms. The motor tolerates frequent acceleration cycles and supports industry-standard microstepping drives for smooth velocity transitions. Its low inductance and thermal resistance enable extended duty cycles with minimal risk of thermal buildup.

System integration is streamlined through compatibility with Kollmorgen P7000 series stepper drives, which deliver closed-loop indexing, programmable profiles, and torque control. The CTM31NLF09KAA00’s compact dimensions and connector configuration reduce cabinet space and wiring complexity. Target applications include precision packaging machines, semiconductor handling equipment, medical diagnostic devices, and pick-and-place robotics where accurate, repeatable motion is paramount. As part of Kollmorgen’s CT Stepper Motors line, this model combines ease of integration with the performance demanded by modern automated systems.
