YE5 (IE5)
YE5 (IE5) Series Three-Phase Induction Motor
The top induction efficiency class LEADGO builds — grade 1 under GB 18613—2020, IE5 under IEC 60034-30-1:2025, in standard IEC frames.

YE5 is a single-speed, totally enclosed, fan-cooled, continuous-duty low-voltage squirrel-cage induction motor reaching grade 1 of GB 18613—2020, corresponding to IE5 in IEC 60034-30-1:2025.
It matters most where the machine runs close to rated load for most of the year. On that duty an IE5 induction motor is frequently the lower-total-cost answer against a permanent magnet machine, because it needs no drive to reach its rated efficiency.
