Product Description:
The E32Nrlp-Lnn-Ns-00 is a hybrid stepper motor produced by Kollmorgen for the E Hybrid Stepper Motors series. This two-phase device integrates SIGMAX magnetic construction and dual rotor stacks to generate discrete angular increments. In automated machinery, it provides open-loop indexing by translating command pulses from a microstep drive into precise shaft movement without a feedback transducer, making it suitable for positioning tables, labeling heads, or light-duty actuators. The Class B insulation system permits winding temperatures up to 130 °C under continuous duty.
At the mechanical interface, the motor occupies the NEMA 34 frame, and its housing length is limited to 95.5 mm so it fits standard 86 mm square flanges. A static holding torque of 4.75 Nm keeps loads in place when the energized motor is at a standstill, while each full step covers 1.8 degrees, yielding 200 discrete positions per revolution for predictable motion profiles. Electrically, the windings draw 4.1 A per phase at a resistance of 0.74 Ω, and the phase inductance is 8.9 mH. These parameters guide the selection of drive voltage and chopping frequency so the current reaches its setpoint within microsecond time frames. Insulation resistance is 100 megohms, and the system tolerates 340 VDC between the windings and frame.
Dynamic behavior is supported by an allowable axial load of 801 N and a rotor inertia of 0.000120 kg·m², balancing speed response against cogging for smooth low-speed operation. Thermal management relies on a case-to-ambient thermal resistance of 2.7 °C/W, enabling continuous service across an ambient temperature range of -20 °C to +40 °C without derating. Radial bearing load capacity is 156 N, and the mechanical error per full step remains within ±1.5%, supporting repeatable positioning during operation. The smooth 9.53 mm shaft accepts custom couplings, and the overall mass of 2.40 kg supports gantry or belt-driven installations where moving weight must be minimized.
