Product Description:

The H22NREC-LDN-NS-00 hybrid stepper motor is produced by Kollmorgen within the H Hybrid Motors series. Intended for open-loop positioning tasks, it converts pulse commands from indexers or microstep drives into incremental shaft motion for material-handling stations, labeling heads, and light gantry axes. By blending permanent-magnet and variable-reluctance design principles, it delivers discrete angular steps without a feedback element, streamlining motion systems that need repeatable positioning without closed-loop circuitry. This arrangement suits equipment that relies on straightforward drive control and repeatable indexing during frequent start-and-stop motion.

The motor uses a NEMA 23 frame size and follows the standard NEMA mounting template, while its external diameter measures 2.25 in. The rotor advances 1.8 degrees per full step, giving 200 steps per revolution. Positional deviation is limited to ±1.5 %, which supports consistent indexing over long travel. Six pre-terminated lead wires form the regular connection style, and the 6-lead architecture allows either series or parallel winding links. Dual rotor stacks increase torque density, while the laminated rotor core reduces eddy-current losses. With no internal feedback, the motor pairs with drives that regulate phase current rather than monitor rotor position, keeping control hardware simple.

Thermal and dielectric limits set the safe operating envelope. The windings use Class B, 130 °C insulation, the dielectric withstand rating reaches 340 Vdc, and insulation resistance is 100 Megohms when tested at ambient conditions. Ambient service conditions may range from –20 °C to +40 °C, allowing use in unheated assembly cells. Standard construction uses a smooth shaft and no shaft seal, so the motor should be installed away from liquid spray. These characteristics suit dry indoor indexing and transfer applications where compact packaging and simple electrical hookup are important.
