Product Description:

The H2HNRFB-LNN-NS-00 is a hybrid stepper motor produced by Kollmorgen in the H Hybrid Motors series. It merges permanent-magnet and variable-reluctance technology to deliver precise incremental motion for industrial axes that require repeatable open-loop positioning. A laminated rotor, smooth single shaft, and standard construction allow straightforward coupling to NEMA mounts found on pick-and-place heads, index tables, and compact conveyors, where static holding torque is needed without embedded feedback. Standard leadwire terminations simplify panel wiring, and external encoders can be added when closed-loop verification is required.

The motor uses the NEMA 23 frame size, which aligns with common miniature stage patterns. Each command pulse advances the rotor by 1.8 degrees, so 200 full steps produce one revolution when micro-stepping is disabled. Stator insulation withstands up to 340 Vdc, giving ample margin when driven from high-bus choppers. Continuous duty is permitted from -20 °C to +40 °C, making cold-room starts and normal shop-floor operation feasible. An 8-lead harness exits the housing, allowing the phases to be wired in series or parallel to match drive current and voltage requirements.

The housing diameter measures 2.25 in, which matches the frame designation and eases clamp-style gearbox attachment. Dry winding insulation remains above 100 Megohms, which helps minimize leakage that could trip ground-fault monitors. Mechanical tolerance keeps each step within ±1.5% of its nominal increment, helping control cumulative error during multi-turn sequences. The windings allow bipolar series/parallel connection, so the motor can be configured for higher inductance at low speed or lower inductance for faster indexing without changing the hardware.
