Product Description:

The E22NRFD-LNN-NS-00 hybrid stepper motor is produced by Kollmorgen as part of the E Hybrid Stepper Motors series. This two-phase motor combines permanent-magnet and variable-reluctance principles to deliver incremental motion for indexing tables, small conveyors, and pick-and-place axes that do not require encoder feedback. Its NEMA mounting pattern simplifies interchange with other 56 mm (2.25 in) motors, and the single smooth shaft lets couplings or pulleys be fitted without extra machining, making the unit a straightforward positioning element in automated equipment.

The motor’s mechanical footprint follows a NEMA 23 frame, giving a 2.25 in outside diameter that aligns with standard clamps and gearheads. Each full step advances the rotor by 1.8 degrees, giving a native resolution suited for moderate-precision positioning before microstepping is applied. A flexible 8 lead connection style supports series or parallel phase wiring, allowing torque and current to be matched to the available drive. Electrical isolation is reinforced by an insulation resistance of 100 Megohms at 25 °C, which helps limit leakage in humid environments. Performance is supported by SIGMAX construction, a laminated stator design that concentrates flux for higher torque density while keeping detent torque low. The rotor is laminated in a two-stack design and runs without a shaft seal, so external protection is advised when fluids are present.

The motor can operate continuously from -20°C to +40°C, enabling use in unconditioned panels or lightly cooled machinery. The windings use Class B, 130°C insulation, so thermal headroom remains even during extended dwell at standstill. Step accuracy is held within +/- 1.5 %, which is useful for fixtures where repeatability matters but closed-loop feedback is unnecessary. With 200 discrete steps per revolution, the motor works with microstepping drives for finer angular increments. The regular lead-wire harness, NEMA mounting style, and absence of feedback simplify installation.
