Motor Description

The YE3-4501 achieves IE3 efficiency compliance under GB 18613-2020 and IEC 60034-30-1, validated through rigorous GB/T 1032 input-output testing. Designed with high-strength cast iron frames and corrosion-resistant copper windings, these motors offer exceptional durability in aggressive or high-humidity environments. IP55-rated enclosures (IEC 60034-5) and IC411 cooling ensure reliable heat dissipation for continuous S1 duty cycles.

Optimized for energy conservation, they integrate seamlessly into hydraulic systems, agricultural machinery, and eco-friendly projects via IEC 60072/GB/T 4772.1-compliant mounting. Advanced electromagnetic design minimizes operational losses while maintaining low noise and vibration levels. Certified to GB/T 28575 and JB/T 8 standards, the YE3 series replaces legacy Y/YE2 motors, delivering higher efficiency, reduced downtime, and compliance with global green protocols. Ideal for food processing, wastewater treatment, and industrial automation, where precision, compact design, and sustainability are paramount.
