Product Description:
The H22NRHT-LNF-NS-02 is a hybrid stepper motor produced by Kollmorgen within the H Hybrid Motors series. This NEMA-23 device provides incremental positioning in automated machinery such as pick-and-place heads, indexing tables, and small gantry axes. By synchronizing rotor teeth with discrete stator energization states, it converts digital pulse trains from the drive into controlled angular motion without requiring a feedback transducer. Its construction supports direct panel mounting and integrates easily into multi-axis stages where compact size and repeatable step accuracy are important.
The motor has an outside frame diameter of 2.25 in, matching the bolt circle of standard NEMA-23 mounts while keeping inertia low for quick response. Each energization increment advances the shaft by 1.8 degrees, giving uniform angular resolution well suited to micro-stepped control. Power enters through a 4-lead parallel harness of black, orange, red, and yellow conductors, allowing two-phase excitation that maximizes current sharing between the dual stacks. The motor is specified for ambient operation from -20 °C to +40 °C, so enclosed panels must stay within that thermal window. A smooth single shaft simplifies coupling to pulleys or flexible couplers, and the laminated rotor limits eddy losses during rapid indexing.
Electrical insulation is rated at Class B, 130 °C, providing a safe thermal margin above the external temperature limit, and insulation resistance of 100 Megohms helps prevent leakage when the winding is driven from high-voltage controllers up to the 340 Vdc withstand level. The rotor can hold 200 discrete positions per mechanical turn, supporting open-loop precision within the stated ±1.5% step accuracy. The laminated core works with the two-stack design to raise detent torque, while the winding is optimized for maximum torque at low speed so the motor can deliver high holding force during stall without added gearing. These traits suit feed axes that dwell for long periods yet demand immediate incremental motion.
