YVFE2-280M-6 Manufacturer: VFD High-Efficiency Motor: Principle, Harmonics & Flexible Speed

2026-09-14 · XIMA Motor Technical Center

YVFE2-280M-6 manufacturer explains VFD high-efficiency (55kW) principle, forced cooling, harmonics and FAQ.
For "what is YVFE2-280M-6, how to select it, what are its parameters": in short, YVFE2-280M-6 is a LV VFD high-efficiency 3-phase induction motor for flexible speed control from XIMA. It is composed of series YVFE2 + frame 280M + 6 poles. When selecting, verify power, voltage, cooling (IC416 (forced vent.) or IC411), protection (IP55) and efficiency (up to IE4 (VFD duty)), and have the manufacturer confirm the design and factory tests.

1. What is YVFE2-280M-6? How to read the model

YVFE2-280M-6 is a LV VFD high-efficiency 3-phase induction motor for flexible speed control from XIMA. Its model follows "series code + frame center height + poles": YVFE2 is the series (LV variable-frequency drive 3-phase induction motor (high-eff)), 280M is the frame center height (mm), 6 is the pole count (rated speed approx. 980 r/min).

Note: writing only "YVFE2" is just a series name, not a complete model. A real motor model must include the frame and poles, e.g. YVFE2-280M-6 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

  • YVFE2 is VFD high-efficiency, optimized for converter supply, 5–50 Hz constant torque, 50–100 Hz constant power.
  • Independent shaft-mounted blower (IC416) keeps cooling at low speed; optional encoder for closed-loop.
  • 280M frame, 6-pole, 55 kW for hoisting, machine tools, textile, paper requiring wide speed range.
  • Corona-resistant insulation and filtering suppress converter dv/dt and harmonics, extending winding life.

4. How to choose YVFE2-280M-6 vs YVF2

Within XIMA's portfolio, YVFE2-280M-6 differs from the comparison series in cooling, efficiency and starting method. Choose by duty priority:

八、常见问题 FAQ

Q:YVFE2-280M-6 as ordinary motor?
A:Yes, but higher efficiency under VFD; for long constant-frequency use YE series is better.
Q:Why forced ventilation?
A:At low VFD speed self-fan airflow drops; independent blower (IC416) protects winding.
Q:YVFE2 vs YVF2?
A:Energy-saving/high-eff choose YVFE2; general choose YVF2.
Q:Need encoder?
A:High speed/position accuracy (machine tool, winding) — recommend encoder closed-loop.
