Description
Product Overview
Pacific Scientific E33NRHA‑LNN‑NS‑00 belongs to E‑Series Sigmax hybrid stepper motor family, now under Kollmorgen brand ownership. Adopting Sigmax high‑performance magnetic‑circuit design, this NEMA34 frame stepper provides outstanding holding torque and acceleration performance compared with ordinary hybrid stepper motors. It uses connector‑style termination instead of flying leads, single smooth shaft and 3‑stack rotor construction, widely used for legacy automation equipment spare‑part replacement for multi‑axis positioning platforms, packaging machinery and material‑handling systems.
Series
E‑Series Sigmax stepper motor is Pacific Scientific classic high‑torque stepper platform. The Sigmax magnetic‑circuit greatly improves torque‑to‑volume ratio. Multiple frame sizes and stack‑length options are available for different torque‑demand automation equipment, supporting various termination and shaft configurations for field‑wiring requirements.
Product Features
‑ Sigmax optimized magnetic‑circuit technology for higher torque and acceleration output‑ NEMA34 standard flange mounting, 3‑stack rotor structure for high‑holding‑torque output‑ 1.8° step angle (200 steps/rev), high positioning repeatability‑ LNN termination: internal receptacle connector, no loose flying leads, stable field connection‑ Single smooth shaft configuration, convenient for coupling installation‑ Bipolar winding design, compatible with matching Pacific Scientific / Kollmorgen stepper drives‑ Rugged industrial mechanical structure, suitable for cabinet‑mount industrial equipment environment‑ End‑of‑life product; only new‑old‑stock / refurbished spare‑part supply for existing‑machine maintenance
