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.

IE50.55–315 kWIP55
YE series three-phase induction motor

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.

Standards and certification

  • GB 18613—2020 grade 1
  • IEC 60034-30-1:2025 IE5 (IE5 was introduced in the 2025 second edition)

Typical applications

  • Crushers and storage conveyors running at constant speed near rated load
  • Continuous process fans and pumps with high annual operating hours
  • Sites where the efficiency class is written into the specification

Selection guide

Constant-speed, high-utilisation duty. Few failure points, high efficiency and strong momentary overload capability, with no drive required.
For constant-speed duty running near rated load, evaluate YE5 first — the capital cost is lower and no drive is needed. Where the duty is variable-speed or involves frequent starting, a permanent magnet machine holds its advantage across the whole load range.
