Product Description:
The E33NCEA-LNN-NS-00 is a hybrid stepper motor manufactured by Kollmorgen within the E Hybrid Stepper Motors series. Designed for incremental positioning and low-speed torque duties in automated tables, indexers, and small gantries, this three-stack model converts digital pulse commands into precise shaft rotation without relying on an encoder. Its SIGMAX construction concentrates magnetic flux, helping the motor deliver repeatable steps while maintaining the thermal limits established by its Class B insulation system.
The motor is built on a NEMA 34 frame, so it mounts directly to standard 86 mm face plates used in actuators and gearheads. A holding torque of 4.69 Nm keeps loads stationary whenever pulses stop, and each phase can be driven at 6.1 A to reach that torque without saturation. With a basic step angle of 1.8 degrees, the rotor advances in 200 steps per revolution, simplifying microstepping calculations. Low rotor inertia of 0.025 oz-in-s² allows fast acceleration, while step accuracy remains within ±1.5% because the three stator stacks share identical electrical constants. Six leads exit through a System MS connector, allowing the phases to be wired in series or parallel to match the available drive voltage.
The shaft can withstand an axial load of 180 lb and a radial load of 35 lb, enabling the motor to carry moderate belts or lead screws without additional support bearings. A phase resistance of 0.46 ohms limits copper losses at the rated current, and the comparatively low inductance of 2.3 mH permits rapid current rise for responsive step transitions. The electrical insulation resists up to 340 V DC and maintains 100 MΩ of isolation. A thermal resistance of 2.0 °C/W helps the winding remain within its operating temperature range of -20 °C to +40 °C. The smooth 0.500-inch shaft simplifies coupling alignment, and the motor weighs 7.6 lb, making it suitable for gantry mounting.
