Product Description:

The E31NCLT-LNN-N8-00 is a hybrid stepper motor produced by Kollmorgen within the E Hybrid Stepper Motors series. Built on SIGMAX construction, the unit translates discrete step commands from indexers or microstepping drives into open-loop rotary motion for positioning tables, metering pumps, and other mid-torque automation axes. Its NEMA mounting style matches common gearboxes and brackets, allowing straightforward installation in industrial machinery. The motor supplies repeatable incremental motion without feedback devices, making it suitable for fixed-index duties in packaging, semiconductor, and life sciences equipment.

With a frame size of NEMA 34, the motor delivers a holding torque of 2.38 Nm from a single-stack winding optimized for maximum torque at low speed. The four-lead series configuration draws a rated phase current of 2.7 A. Its coils have a phase resistance of 1.12 ohms and an inductance of 10 mH, which affect driver voltage requirements and current-loop dynamics. A 1.8-degree step angle produces 200 discrete positions per revolution, and the step accuracy remains within ±1.5 percent for repeatable indexing. The electrical insulation is rated Class B at 130 °C, withstands 340 VDC, and provides 100 megohms of resistance to ground.

The smooth shaft tolerates an axial load of 801 N and a radial load of 156 N, enabling direct coupling to pulleys or lead screws without premature bearing wear. The rotor inertia of 0.0083 oz-in-s² supports quick acceleration, while the thermal resistance from the case to the surrounding air is 3.9 °C/W to help the housing dissipate heat. Continuous operation is permitted at ambient temperatures from -20 °C to +40 °C. The motor weighs 1.45 kg, reducing gantry payload while retaining the stiffness expected from this frame class. Power reaches the single-stack winding through the System MS connector, and the SIGMAX magnetic path improves detent torque consistency.
