Product Description:
The E2HNRHB-LNF-NS-02 belongs to the E Hybrid Stepper Motors series manufactured by Kollmorgen. It is a two-phase hybrid stepper motor intended for positioning or speed-indexed tasks in industrial automation, where a drive issues discrete step commands and the motor advances by a fixed mechanical increment. The NEMA mounting interface fits established machine frames, and the smooth shaft profile simplifies coupling to gearheads, timing pulleys, or direct-drive loads without keyway machining. This configuration supports applications such as indexing tables, conveyor adjustments, laboratory equipment, and compact material-handling systems that require controlled incremental motion.
The motor advances by a fixed 1.8 degrees per electrical step, which results in 200 full steps per revolution and provides its basic open-loop resolution. Rotor and stator tolerances limit deviation to a step accuracy of ±1.5%, keeping position error low in indexers or small-angle oscillators. A square NEMA 23 frame concentrates the magnetic circuit while fitting common 57 mm mountings. Electrical access is provided through a four-lead parallel winding set suitable for connection to a compatible bipolar stepper drive. Leads exit the housing through a regular lead wire connection, allowing splice joints or screw-terminal attachment inside a cable tray. The NEMA mounting style holds the front face flat against a panel, while SIGMAX construction shortens the magnetic path to improve torque output and detent stiffness.
The thermal operating range extends from -20 °C to +40 °C. An insulation voltage of 340 VDC withstands transients that may appear on unfiltered stepper drives, and the windings maintain an insulation resistance of at least 100 megohms at ambient humidity. Class B insulation tolerates winding temperatures up to 130 °C, supporting continuous stall conditions and high-duty operating cycles. SIGMAX laminations reduce electrical losses, which helps limit heat generation during operation. The regular lead wire exit keeps the electrical connections outside the motor frame, leaving the housing surfaces unobstructed for heat dissipation. Open-loop operation allows the motor to maintain commanded incremental movement without an additional position-feedback device when load torque remains within the available operating range.
