Motor Description

YE3-4003 motor meets IE3 efficiency standards (GB 18613-2020/IEC 60034-30), certified via GB/T 1032 input-output testing for precision. Constructed with reinforced cast iron housing and F-class insulated copper windings, these motors ensure resilience in corrosive or high-load environments. Aligned with IP55 protection (IEC 60034-5) and dual cooling modes (IC411/IC416), they maintain stable thermal performance under continuous S1 duty.

Engineered for diverse industrial applications, the motors reduce harmonic distortion and electromagnetic interference, enhancing compatibility with precision-driven systems like packaging machinery, textile equipment, and renewable energy installations. Compliant with IEC 60072/GB/T 4772.1 mounting specifications, they enable effortless retrofitting to replace inefficient Y/YGM/YE2 models. Backed by rigorous GB/T 28575/JB/T 8 validation, the YE3 series delivers up to 25% lower energy consumption, extended thermal tolerance, and compliance with global sustainability mandates. Ideal for high-efficiency retrofits in mining, chemical processing, and smart manufacturing, where reliability and eco-performance are critical.
