Product Description:
The E42HLLB-LNK-NS-02 is a hybrid stepper motor manufactured by Kollmorgen within the E Hybrid Stepper Motors series. It combines permanent-magnet torque with variable-reluctance alignment to generate precise incremental motion for indexing tables, pick-and-place gantries, and other automation axes where encoder feedback is optional. The motor accepts standard step-and-direction commands and converts them into incremental shaft movement, enabling predictable positioning throughout its electrical rotation.
The mechanical envelope follows the NEMA 42 frame code, giving the motor a 4.28-inch body diameter, a 3.000-inch mounting bolt circle, and a 2.186-inch pilot for compatibility with heavy-duty NEMA brackets. A splash-proof conduit entry uses a 1/2-inch NPS pipe thread and routes the four-lead series connections to the terminal board. Dual-stack SIGMAX construction increases magnetic flux and helps the rotor deliver 2600 oz-in of holding torque while maintaining a low inertia of 0.16 oz-in-s². Each electrical step advances the shaft by 1.8 degrees, and typical positioning error is limited to ±1.5%. The phase circuit has an inductance of 21.7 mH and a resistance of 1.07 ohms, allowing compatible drive amplifiers to apply suitable current-decay and microstepping profiles.
The bearing system supports an axial thrust of 400 lb and a radial load of 140 lb when the smooth shaft is coupled directly to belts or gears. Each phase can be driven with 4.9 A, while the winding-to-case thermal resistance remains 1.3 °C/W and the Class B insulation withstands winding temperatures up to 130 °C. The motor has a dielectric strength of 340 VDC and an insulation resistance of 100 MΩ, and it can operate at ambient temperatures from -20 °C to +40 °C in washdown enclosures. The electrical cycle provides 200 steps per revolution, giving automation axes uniform positioning resolution without external gearing.
