YE3/YE4 Super Premium Efficiency Motor

Overview

The YE3 / YE4 super-premium efficiency motor (frame H80–H355) is a low-voltage, totally-enclosed, fan-cooled squirrel-cage motor meeting national and IEC efficiency standards. Efficiency complies with Grade 1 of GB/T 18613 and aligns with IEC 60034-30 IE3 / IE4, fully replacing Y, Y2 and YE2 series. It is the preferred drive for industrial energy-saving retrofits and equipment upgrades.

Applications

• General industry: machine tools, pumps, fans, compressors
• Material handling: conveyors, transport equipment
• Manufacturing: mixers, printing equipment
• Agriculture & food: farm machinery, food processing lines

Technical Highlights

• Low-loss silicon steel and optimised slot combination cut iron & stray losses
• ~10% higher efficiency than standard Y2, greatly lowering energy cost
• Class F insulation rated by Class B rise, with ample margin
• H280–355 frames fitted with grease-relief devices for easy maintenance
• Rugged, low-noise, low-vibration, stable long-term operation

Operation & Environment

Ambient temperature -15℃ to 40℃; altitude ≤1000m; rated voltage 380V / 660V, 50Hz; stable within ±5% voltage and ±1% frequency variation; IP55 protection, IC411 cooling, S1 duty.
