Description
The YE5 series is an ultra-high efficiency (IE5) three-phase asynchronous AC induction motor, fully compliant with international standard IEC 60034-30-1 and China’s GB 18613-2020 (Level 1) energy efficiency requirements. As an upgraded successor to YE3 and YE4 series, it adopts a fully enclosed fan-cooled (IC411) structure with a squirrel-cage rotor and robust cast iron frame, setting a new benchmark for industrial energy conservation.
With frame sizes ranging from H80 to H355 and power ratings spanning 0.55kW to 315kW, the series operates at a standard 380V/50Hz (customizable voltage/frequency available) for continuous duty (S1). Key specifications include Class F insulation and IP55 protection rating (IP56/IP65 optional for harsh environments), ensuring reliable operation in temperatures from -15℃ to 40℃ and altitudes below 1000 meters. Its optimized electromagnetic design integrates low-loss electrical steel laminations and high-quality copper windings, reducing energy consumption by approximately 20% compared to IE4 motors and maintaining high efficiency across 20%–120% load ranges.
Core advantages of the YE5 series include minimal noise, low vibration, strong starting torque, and IEC-compliant mounting dimensions for seamless retrofitting. The motor’s low temperature rise extends service life, while its robust construction withstands demanding conditions in industries like petrochemicals, steel, mining, and water treatment. It is ideally suited for driving pumps, fans, compressors, conveyors, and machine tools, serving as a cost-effective solution for green factory upgrades and energy-saving transformation projects.
