YE4 three-phase induction motor

CATALOGUE OVERVIEW

About this motor series

Shiyang’s YE4 brochure specifies 0.55–355 kW, 80–355 mm centre heights and a 380 V / 50 Hz supply. It lists IP55, F-class insulation with B-class temperature-rise limits, continuous duty and IC411 cooling. The brochure’s efficiency wording is inconsistent: the introductory text and parameter line do not identify the same efficiency grade. Confirm the efficiency test report for the exact ordered motor rather than relying on the series label.

The official brochure has conflicting efficiency-grade wording. No verified efficiency class is assigned from that line.
