For "what is YE3-180M-4, how to select it, what are its parameters": in short, YE3-180M-4 is a LV IE3 high-efficiency 3-phase induction motor, 18.5 kW mainstream frame from XIMA. It is composed of series YE3 + frame 180M + 4 poles. When selecting, verify power, voltage, cooling (IC411 (self-ventilated)), protection (IP55) and efficiency (IE3 (GB 18613-2020 grade-3, mandatory)), and have the manufacturer confirm the design and factory tests.
1. What is YE3-180M-4? How to read the model
YE3-180M-4 is a LV IE3 high-efficiency 3-phase induction motor, 18.5 kW mainstream frame from XIMA. Its model follows "series code + frame center height + poles": YE3 is the series (LV 3-phase induction motor (IE3 high-efficiency)), 180M is the frame center height (mm), 4 is the pole count (rated speed approx. 1480 r/min).
Note: writing only "YE3" is just a series name, not a complete model. A real motor model must include the frame and poles, e.g. YE3-180M-4 or YE5-90L-6. Within XIMA's catalog, different frames/poles under the same series mean different power and mounting dimensions — always order by the full model.
