Product Description:
The E32NRHP-LNN-NS-00 hybrid stepper motor is built by Kollmorgen for the E Hybrid Stepper Motors series. As a two-phase actuator with a SIGMAX core, it provides incremental motion for indexing tables, gantries, and packaging axes that require open-loop positioning without an encoder. The motor translates controller pulse streams into discrete shaft rotation, making it suitable for general industrial automation.
With a frame that complies with the NEMA 34 standard, the housing measures 85.85 mm across and 95.5 mm long, so it fits most 34-frame gearboxes and brackets. The motor provides a holding torque of 4.75 N-m, which maintains the shaft position whenever drive current is applied. Each phase is energized at 8.1 A and has a winding resistance of 0.19 ohms. An inductance of 2.2 mH supports the high slew rates required by the winding, which is designed to provide maximum torque at high speed. Each basic step produces 1.8 degrees of shaft movement per pulse, resulting in 200 full steps per revolution and a positioning tolerance of ±1.5%. The SIGMAX construction concentrates magnetic flux in the rotor teeth, increasing dynamic torque while keeping the motor weight at 2.40 kg.
The stator has a thermal resistance of 2.7 °C/W, allowing heat generated by copper losses to dissipate from the windings. The Class B insulation system tolerates winding temperatures up to 130 °C, withstands a 340 VDC high-potential test voltage, and maintains an insulation resistance of 100 megohms. The permitted ambient operating range is -20 °C to +40 °C. The smooth shaft supports an axial load of up to 801 N, while belt-driven applications must keep the radial load within 156 N. The two-stack rotor connects through a standard lead-wire harness containing four parallel leads, each measuring 304.8 mm long. The harness exits through the NEMA-pattern connection area for straightforward cable routing.
