Product Description:
The E42HLHT-LNK-NS-00 is a hybrid stepper motor built by Kollmorgen for the E Hybrid Stepper Motors series. With its NEMA 42 frame and SIGMAX laminated rotor design, this model is targeted at indexers, gantries, and positioning tables that need discrete motion without feedback devices. It converts digital pulse trains from a stepper drive into precise incremental shaft movement, providing open-loop control that is simple to use in industrial automation cells.
It provides a holding torque of 18.0 Nm, enough to keep large mechanical loads in position when pulses stop. During continuous operation, each phase may be driven at 7.9 A; this current works against a phase resistance of 0.41 ohms and a phase inductance of 7.8 mH, so the drive must supply short rise-time current while managing copper losses. The motor advances by 1.8 degrees per full step, resulting in 200 discrete positions per revolution. Combined with a stated step accuracy of ±1.5%, this angular increment supports mid-range speed profiles without closed-loop feedback. The two-stack construction and low rotor inertia of 1.13 × 10⁻³ kg-m² allow rapid acceleration while maintaining synchronous operation with incoming pulse commands.
The mechanical envelope supports an axial load of 1780 N and a radial load of 623 N, making the smooth single-shaft configuration suitable for belt drives or direct-coupled lead screws. Heat is transferred to ambient through a thermal resistance of 1.3 °C/W, and Class B insulation tolerates a 130 °C winding temperature provided the surrounding air remains within -20 °C to +40 °C. A splash-proof conduit entry using a 1/2-inch NPS thread protects the four parallel leads and simplifies heavy-duty NEMA mounting. The motor weighs 8.26 kg, so the supporting structure must account for that static mass while allowing the required step response.
