Product Description:

The E33HRFA-LNK-NS-00 is a hybrid stepper motor produced by Kollmorgen for the E Hybrid Stepper Motors series. This three-stack unit converts drive current into incremental rotary motion, allowing indexed movement without closed-loop feedback. Its SIGMAX construction concentrates magnetic flux, while a heavy-duty NEMA mounting face lets the motor bolt directly onto positioning tables, pick-and-place heads, or other automation frames.

The motor delivers a holding torque of 6.64 N-m, giving reliable static load support at each of the 200 steps produced per revolution. A frame size of NEMA 34 corresponds to an 86 mm square flange and matches standard gearheads and couplings. Each step spans 1.8 degrees, and cumulative positioning error stays within a ±1.5% accuracy range. Eight 22 AWG leads exit the housing in a standard lead-wire style, and their minimum length of 304.8 mm allows direct connection to terminal blocks without extensions. Phase windings present 0.23 Ω of resistance and 2.3 mH of inductance when wired in parallel, so the matched drive must regulate current transients. The rated drive current is 8.6 A per phase, and the 2.0 °C/W thermal path through the stator helps keep coil temperature within limits. A smooth shaft handles radial loads up to 427 N and axial forces up to 801 N, while the overall body length remains within a 135.4 mm maximum.

An operating range of -20 °C to +40 °C makes the motor suitable for unconditioned factory floors. Class B insulation rated to 130 °C withstands winding heat and is supported by 100 MΩ insulation resistance with a 340 Vdc dielectric test voltage. Rotor inertia is 0.177 × 10⁻³ kg·m², allowing quick acceleration when driven by microstepping controllers. The assembly weighs 3.45 kg, which helps damp vibration while remaining manageable for moving gantry axes.
