Motor Description

YE3-4503 motor (H80–H450) meets IE3 efficiency standards (GB 18613-2020/IEC 60034-30-1), certified through GB/T 1032 loss-analysis protocols. Featuring die-cast aluminum rotors and Class-F insulation, the motors achieve superior thermal stability and energy density, ideal for continuous S1 duty in variable-frequency drive applications. IP55-rated enclosures (IEC 60034-5) and IC416 cooling ensure resilience in high-humidity or particulate-heavy environments. Optimized for dynamic load adaptation, these motors reduce no-load losses compared to Y/YE2 models, with precision-balanced rotors minimizing vibration. Compliant with IEC 60072-1 mounting, they retrofit seamlessly into conveyor systems, CNC machinery, and data center cooling units. Validated under GB/T 28575, the series offers adaptive torque control, voltage fluctuation tolerance, and compliance with ISO 50001 energy management systems. Designed for food-grade manufacturing, textile automation, and renewable energy plants, they prioritize silent operation, modular maintenance, and carbon-neutral industrial transitions.
