E31NRFP-LNN-NS-00

The E31NRFP-LNN-NS-00 from Kollmorgen is a precision hybrid stepper motor in the E Hybrid Stepper Motors series, designed for high-performance motion control applications. With 200 full steps per revolution and a step accuracy of ±1.5 %, this motor delivers precise positioning and repeatability for automated equipment. Its 8-lead configuration provides flexible wiring options and optimized torque characteristics, while the robust NEMA frame size of 34 ensures compatibility with standard mounting interfaces. The primary function of the E31NRFP-LNN-NS-00 is to offer reliable, controlled motion for tasks requiring accurate indexing, point-to-point positioning, and repeatable acceleration profiles.

Building on its core motion capabilities, the E31NRFP-LNN-NS-00 features a maximum lead length (L Max.) of 65.5 mm, delivering a compact form factor without compromising performance. The motor’s insulation system boasts a voltage rating of 340 Vdc and an insulation resistance of 100 MΩ, enhancing electrical durability under varying load conditions. The hybrid design combines the benefits of permanent magnet and variable reluctance technologies to yield a high torque-to-inertia ratio, making it uniquely suited for rapid start-stop cycles and dynamic acceleration requirements below 2,000 RPM. The eight-lead harness supports multiple current and voltage wiring schemes, allowing system integrators to fine-tune output torque and current draw according to application demands.

Designed for industrial environments, this stepper motor is built with Class B insulation and is UL recognized, ensuring compliance with safety and electrical standards. The motor’s anodized housing and precision-ground rotor shaft contribute to long-term reliability and low maintenance needs. Its NEMA 34 frame offers straightforward integration with existing motion control platforms, while the standard 200-step resolution supports both open- and closed-loop control architectures. By delivering consistent torque, enhanced electrical protection, and flexible connectivity, the E31NRFP-LNN-NS-00 provides substantial efficiency gains in automated machinery, robotics, and precision positioning systems, reducing downtime and improving overall system throughput.
