450 kW YE3 Series (IE3) motor
450 kW YE3 Series (IE3) Three-Phase Motor
YE3 Series (IE3) (IE3) ratings at 450 kW. 3 frame/pole options are in the catalog at this power.
450 kW ratings
| Model | kW | Frame | Poles |
|---|---|---|---|
| YE3-4003-2 | 450 | 400 | 2 |
| YE3-4003-4 | 450 | 400 | 4 |
| YE3-4003-6 | 450 | 400 | 6 |
Duty and enclosure
Most general-purpose TEFC machines in the catalog are intended for continuous duty (S1) on pumps, fans, compressors, and conveyors. Short-time or intermittent duty, frequent starts, or inverter supply may need a different series (for example YVF2 for VFD or YEJ for brake). Match enclosure (typically IP55 / IC411 TEFC) to dust, moisture, and washdown at the site.
Before you order
- Frame and shaft from the table row, not from kW alone
- Poles vs required r/min
- Enclosure IP55 / TEFC vs site dust and washdown
FAQ
Can the YE3 motor replace my old Siemens, ABB, or WEG IE1 motor?
Yes. The YE3 series strictly adheres to IEC metric frame standards. If your current motor has a standard IEC frame (e.g., frame size 132M, 160L), the YE3 will perfectly align with your existing bolt hole spacing, shaft center height, and flange dimensions. It’s a truly seamless direct replacement.
Is this motor suitable for use with a frequency converter (VFD)?
Yes. Thanks to its Class F insulation and robust winding design, the YE3 series is compatible with frequency converters (VFDs) for variable speed control. For applications with extremely long cables (>50m) or extremely high voltages (>500V), please consult our engineering team for specific filter recommendations.
What is the difference between IE2 and IE3 motors?
The IE3 motor is classified as an “ultra-efficient” motor, meaning it experiences fewer losses when converting electrical energy into mechanical energy compared to the IE2 “efficient” motor. This is achieved through better materials (cold-rolled silicon steel) and optimized design. While the initial cost of an IE3 motor may be slightly higher, its significantly reduced power consumption results in a lower total cost of ownership (TCO).
Which frame should I use for a 450 kW YE3 Series (IE3)?
Frame follows the catalog row for that kW and pole count. Use the table on this page when present, then confirm shaft and feet on the datasheet.
