E31NRLP-LSN-NS-03
by Kollmorgen
The Kollmorgen E31NRLP-LSN-NS-03 is part of the renowned E Hybrid Stepper Motors series by Kollmorgen, designed to deliver precise motion control in industrial automation applications. This NEMA 34 frame size motor offers a 1.8° step angle and achieves 200 full steps per revolution, providing high positional accuracy. With an insulation class of Class B (130 °C) and a DC insulation voltage rating of 340 V DC, it ensures reliable performance under demanding thermal and electrical conditions.
The E31NRLP-LSN-NS-03 features a robust stainless steel construction and supports both 2 Phase or 4 Phase winding configurations, allowing seamless integration with various drive schemes. It operates within a frequency range of 50–60 Hz and accepts an input voltage of 220 V AC. The motor includes a straight keyway for secure mechanical coupling and ensures torque transfer without slip. Its insulation resistance of 100 Megohms and an operating temperature range of –20 °C to +40 °C underscore its resilience in fluctuating environments. Sleek SIGMAX rotor stack design enhances acceleration by optimizing the torque-to-inertia ratio, enabling rapid response in cyclical motion profiles.
Engineered for durability and efficiency, the E31NRLP-LSN-NS-03 is compatible with unipolar and bipolar winding schemes, delivering rated torque of 2.43 Nm at 4.2 A current draw. Weighing 3 kg, the motor balances structural integrity with manageable mass for versatile mounting options. Although feedback options are not included, its step accuracy of ±1.5% under no-load conditions ensures consistent repeatability. The motor’s high insulation class and resistance make it suitable for applications exposed to humidity up to 80%. In industrial settings, its precise stepping performance and robust build enhance system reliability, reduce downtime, and improve overall process throughput.
