Product Description:

The H2HNRFT-LNN-NS-00 is a hybrid stepper motor produced by Kollmorgen within the H Hybrid Motors series. It uses standard construction with a laminated rotor, half-stack geometry, and a single smooth shaft to deliver incremental motion without integrated feedback. Industrial automation systems use this motor for open-loop positioning where repeatable steps and moderate holding torque are sufficient, and its NEMA mounting style allows direct replacement of legacy motors. Its open-loop operation suits applications that do not require encoder-based correction.

This motor uses the NEMA 23 frame size, providing a recognized bolt pattern and body length for machinery such as pick-and-place heads or small indexing tables. Each electrical step advances the shaft by 1.8 degrees, which sets the basic motion resolution before microstepping is applied. Eight stator leads provide series or parallel wiring choices, and the 8 lead configuration uses regular leadwires for simple hookup. Series or parallel wiring also lets the motor be matched to different drive current and voltage ranges. Coil insulation meets Class B, 130 °C limits, supported by 100 MΩ insulation resistance and a dielectric withstand rating of 340 Vdc, so the windings tolerate typical drive voltages while minimizing leakage current. The winding is arranged for high torque at low speed, which suits direct-drive axes.

The cylindrical body measures 2.25 in across, keeping the envelope compact for confined cabinets. It operates reliably from -20 °C to +40 °C, matching most indoor equipment climates. Positional repeatability is held within ±1.5% of a commanded step, and a full revolution is divided into 200 discrete positions to support fine indexing without an encoder. A smooth, unsealed shaft simplifies coupler installation but requires external protection if liquid ingress is possible. Regular leadwire termination and the lack of a shaft seal reduce potential maintenance points in conveyors, labelers, and light-duty actuators.
