For "what is YE4-200L1-2, how to select it, what are its parameters": in short, YE4-200L1-2 is a LV IE4 super-high-efficiency 3-phase induction motor, 30 kW high-speed from XIMA. It is composed of series YE4 + frame 200L1 + 2 poles. When selecting, verify power, voltage, cooling (IC411 (self-ventilated)), protection (IP55) and efficiency (IE4 (GB 18613-2020 grade-2)), and have the manufacturer confirm the design and factory tests.
1. What is YE4-200L1-2? How to read the model
YE4-200L1-2 is a LV IE4 super-high-efficiency 3-phase induction motor, 30 kW high-speed from XIMA. Its model follows "series code + frame center height + poles": YE4 is the series (LV 3-phase induction motor (IE4 super-high-efficiency)), 200L1 is the frame center height (mm), 2 is the pole count (rated speed approx. 2950 r/min).
Note: writing only "YE4" is just a series name, not a complete model. A real motor model must include the frame and poles, e.g. YE4-200L1-2 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.
