Motor Description

The YE3-4001 motor (frame H80–H450) represents premium IE3-class high-efficiency motors, certified under GB 18613-2020 and IEC 60034-30 standards. Engineered with heavy-duty gray cast iron housing and corrosion-resistant copper windings, these motors ensure durability in demanding environments. Compliant with IP55 protection (IEC 60034-5) and cooling modes IC411/IC416, they deliver optimal thermal management and dust/moisture resistance.

Designed for S1 duty cycles, the motors feature minimized electromagnetic loss, enhanced efficiency, and ultra-low vibration/noise levels. Universal mounting compatibility (IEC 60072/GB/T 4772.1) enables flexible installation across industries, including water treatment, HVAC, material handling, and agricultural machinery. As a sustainable upgrade, the YE3 series outperforms legacy Y/YE2 motors, offering extended lifespan, reduced maintenance, and significant energy savings. Ideal for global energy-efficient retrofits, they excel in driving pumps, compressors, and automated systems while meeting rigorous environmental and operational demands.
