Product Description:

The E42HLHT-LSS-NS-02 is a hybrid stepper motor produced by Kollmorgen as part of the E Hybrid Stepper Motors series. Designed for open-loop position control, this NEMA 42 unit translates digital pulse streams into precise shaft increments, allowing machine builders to index tooling, conveyors, or packaging slides without an encoder. SIGMAX magnetic construction improves low-speed torque density so the motor can hold or advance loads predictably in industrial automation cells.

Electrical terminations at the terminal board are splash-proof, and the conduit entry accepts a fitting with a 1/2 in. NPS pipe thread, reducing moisture ingress in washdown areas. The motor uses a NEMA 42 frame that measures 4.28 inches in diameter and mounts on heavy-duty NEMA flanges, providing a standard footprint for gearboxes or coupling hubs. Four parallel leads simplify bipolar driver connections, while the two-stack laminated rotor increases detent flux for higher torque per unit of length. A smooth shaft avoids key stress points when clamping couplings are used. Because no feedback device is fitted, motion is determined solely by commanded step sequences, which keeps the wiring and drive configuration simple.

Thermal and dielectric limits are supported by Class B insulation rated for 130 °C, which withstands continuous winding temperatures while maintaining a resistance to ground of at least 100 megohms under ambient conditions. Insulation between the coil layers withstands up to 340 VDC, supporting high-voltage microstepping drives. The motor operates within an ambient temperature range of -20 °C to +40 °C, enabling use in unconditioned factory areas. Each full step advances the shaft by 1.8 degrees, so one full revolution contains 200 discrete positions. Cumulative positional deviation remains within ±1.5% under the rated load. The windings are configured for maximum torque at low speed, complementing the SIGMAX magnetic path during slow-speed indexing.
