Product Description:
The H2HNRHT-LNN-NS-00 is a hybrid stepper motor produced by Kollmorgen as part of the H Hybrid Motors series. It combines permanent-magnet and variable-reluctance construction to deliver incremental motion for conveyor indexing, small gantries, and pick-and-place axes where digital drives issue open-loop step commands. A laminated rotor and smooth shaft allow straightforward coupling to timing pulleys or spur gears, while the half-stack configuration keeps the housing short. Because no integral feedback device is fitted, the controller tracks the rotor position by counting steps. The winding design is optimized for maximum torque at low speeds in light-duty positioning tasks.
With an outer frame diameter of 2.25 in, the motor fits compact enclosures while meeting the NEMA 23 face dimensions for direct mounting. The stator windings have Class B insulation rated to 130 °C, permitting continuous winding temperatures up to that limit before derating is required. Dielectric strength is rated at 340 VDC, so the phase leads can tolerate typical drive-induced transients without insulation breakdown. Electrical hookups use a four-lead parallel connection that lowers resistance and supports higher current for increased low-speed torque compared with series wiring. Insulation resistance is rated at 100 megohms, limiting leakage current when moisture is present. The regular lead wire connection routes black, orange, red, and yellow conductors through a flexible jacket for termination at screw terminals.
Each command pulse advances the rotor by 1.8 degrees, and the laminated core provides 200 discrete positions per revolution. Positional repeatability remains within ±1.5%, allowing cumulative error over multi-turn moves to be estimated without an encoder. The motor tolerates ambient temperatures from -20 °C to +40 °C, enabling operation in unheated warehouses or cabinet spaces with modest ventilation. Its physical configuration includes standard face mounting and no shaft seal, allowing the driven mechanism to use external bearings or a separate seal when needed.
