Product Description:
The E42HLHC-LNK-NS-00 hybrid stepper motor is produced by Kollmorgen within the E Hybrid Stepper Motors series. As a NEMA 42 size actuator, it converts pulse trains from an indexer or drive into discrete angular movement for positioning tasks on conveyors, labeling heads, and small gantry axes. The design couples two-phase electromagnetic windings with high-energy magnets to deliver incremental rotation while holding position without encoder feedback, making it suitable for open-loop industrial automation stages.
At continuous stall, the motor develops 19.1 Nm of holding torque, generated by SIGMAX lamination geometry that concentrates flux in the two-stack rotor. Electrical power is supplied through a four-lead parallel circuit that accepts 14.7 A per phase. Low copper losses are aided by a phase resistance of 0.12 Ω and an inductance of 2.7 mH, allowing current to rise rapidly when step commands change. The two magnetic stacks and NEMA 42 frame result in an overall length of 204.22 mm while keeping rotor inertia at 1.13 × 10⁻³ kg·m², balancing acceleration with damping. Heat conducted from the windings passes through the housing at a thermal resistance of 1.3 °C/W, assisted by the heavy-duty NEMA flange that bolts directly to machinery.
The shaft is rated for 1780 N of axial thrust and 623 N of radial load, making it suitable for belt drives or lead screws mounted at either end of the smooth shaft. A splash-proof conduit entry uses a ½-inch NPS thread to route cabling to the terminal board. The Class B insulation system has a resistance of 100 MΩ and withstands 340 VDC high-potential tests. Continuous service is permitted from -20 °C to +40 °C, and the step increment of 1.8 degrees provides 200 discrete positions per revolution with an accuracy of ±1.5%. Despite the steel rotor and heavy housing, the unit weighs 8.26 kg, enabling overhead mounting without excessive support hardware.
