Motor Description

The YE3-3553 high-efficiency three-phase asynchronous motors comply with international energy efficiency standards, achieving IE3 efficiency class per IEC 60034-30-1 and GB 18613-2020. Designed for durability, the motors feature robust gray cast iron casings, corrosion-resistant copper windings, and IP55 protection (IEC 60034-5), ensuring reliable operation in harsh environments. With cooling modes IC411/IC416 and mounting dimensions conforming to IEC 60072/GB/T 4772.1, they support seamless integration into diverse systems.

Optimized for S1 duty cycle, these motors deliver low energy loss, high efficiency, smooth operation, and reduced noise/vibration. Ideal for pumps, fans, compressors, conveyors, and machinery in industrial, agricultural, and energy-saving applications, they replace outdated Y/YE2 series motors. Combining advanced design with extended service life, the YE3 series excels in performance, sustainability, and cost-effectiveness for global energy conservation initiatives.
