Product Description:
The H33NSHA-LNN-NS-02 hybrid stepper motor is produced by Kollmorgen within the H Hybrid Motors series. With a NEMA 34 frame and standard construction, the unit fits directly on common machine plates through the matching NEMA mounting style. A smooth shaft interfaces with couplings or pulleys, and three laminated stacks generate the electromagnetic field needed for 200 discrete steps per revolution. These traits allow the motor to position light conveyors, indexing tables, or metering pumps precisely in automated assemblies.
Its holding torque is 4.70 Nm, which is sufficient to resist back-driving when power is removed. Each full step covers 1.8 degrees, and the ±1.5% step accuracy helps limit cumulative position error over long sequences. The windings draw up to 8.6 A/phase through a 4-lead parallel connection. Low copper impedance, shown by a phase resistance of 0.23 Ohms and an inductance of 2.7 mH, supports quick current rise for high micro-stepping rates. A rotor inertia of 0.177 ×10⁻³ kg·m² helps reduce load-to-load settling time, while the thermal path of 2.0 °C/Watt and a 340 Vdc insulation rating protect the coil varnish. Insulation resistance remains above 100 megohms, which helps prevent leakage in humid cabinets.
Mechanical side loads are tolerated up to 801 N axially and 156 N radially, allowing belt tensioning or helical gearing without premature bearing wear. Continuous service is allowed from -20°C to +40°C, and the winding system uses Class B, 130°C insulation so thermal margin is maintained near the upper ambient limit. The device weighs 3.45 kg, which is light enough for moving-gantry axes while still adding useful mass for vibration damping. The motor is intended to be mounted to a heat-sinking steel plate so heat can move away from the housing during operation.
