Motor Description

YE3-4502 motor (H80–H450) fulfills IE3 efficiency requirements per GB 18613-2020 and IEC 60034-30, verified via stringent GB/T 1032 loss-analysis testing. Engineered with die-cast aluminum end shields and Class-H insulation, these motors enhance structural stability and thermal endurance for prolonged S1 duty cycles. IP55 protection (GB/T 4942.1) and IC416 cooling ensure adaptability to high-temperature or dusty environments. Tailored for precision industries like pharmaceuticals and petrochemicals, the motors feature optimized magnetic circuits to suppress stray losses, achieving higher efficiency at partial loads. Compliant with IEC 60072-1 shaft heights, they enable direct replacement of Y2/YEJ series units in retrofit projects. Certified under GB/T 28575 and JB/T 8, the YE3 series reduces lifecycle costs through minimized maintenance and adaptive voltage tolerance. Ideal for smart grids, HVAC systems, and offshore platforms, where silent operation, compact footprint, and IECEx compliance drive sustainable industrial transitions.
