For "what is YVF2-225M-4, how to select it, what are its parameters": in short, YVF2-225M-4 is a LV general VFD 3-phase induction motor, the most widely used speed-control spec from XIMA. It is composed of series YVF2 + frame 225M + 4 poles. When selecting, verify power, voltage, cooling (IC411 / IC416), protection (IP54 / IP55) and efficiency (general VFD (up to IE3)), and have the manufacturer confirm the design and factory tests.
1. What is YVF2-225M-4? How to read the model
YVF2-225M-4 is a LV general VFD 3-phase induction motor, the most widely used speed-control spec from XIMA. Its model follows "series code + frame center height + poles": YVF2 is the series (LV general variable-frequency drive 3-phase induction motor), 225M is the frame center height (mm), 4 is the pole count (rated speed approx. 1480 r/min).
Note: writing only "YVF2" is just a series name, not a complete model. A real motor model must include the frame and poles, e.g. YVF2-225M-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.

3. Key technical highlights
- YVF2 is general VFD motor for mainstream inverters, wide freq range (typ. 5–50 Hz constant torque) for fan/pump retrofits.
- 225M frame, 4-pole, 45 kW most common mid-power spec for conveyors, fans, pumps.
- Reinforced insulation/bearing against VFD harmonics and shaft current; optional IC416 for low-speed high torque.
- VFD vs throttling valves saves 20%–50% — top industrial retrofit.
4. How to choose YVF2-225M-4 vs YVFE2

八、常见问题 FAQ
Q：YVF2-225M-4 vs ordinary Y?
A：YVF2 insulation/structure reinforced for VFD; ordinary Y overheats at low VFD speed.
Q：VFD saving?
A：Fan/pump from throttling to VFD typically saves 20%–50%.
Q：45 kW 2 or 4 pole?
A：By load speed: most fans/pumps 4-pole; high-speed 2-pole.
Q：YVF2 vs YVFE2?
A：General saving YVF2; high-eff precise YVFE2.
