YE3 Series (IE3) IEC frame 71 motor
YE3 Series (IE3) IEC Frame 71 Three-Phase Motor
YE3 Series (IE3) in IEC frame 71. This frame is quoted from the datasheet for this series (no row extract in the plugin catalog). Send nameplate kW, poles, voltage, and mounting with the enquiry.
At a glance
IEC frame 71
Confirm H, feet and shaft on the datasheet.
IE3
YE3 Series (IE3) — match poles and kW from the table or nameplate, not from frame alone.
Poles
Speed follows pole count at 50/60 Hz. Confirm the driven machine.
Ratings
Catalog rows for this frame are not in the extract. Use the product page or quote with the nameplate.
IEC mounting and replacement
IEC metric motors in this range use standardized shaft center height (H) and foot-mounting hole spacing so a same-frame replacement typically bolts to the existing base without machining. Confirm H, B, shaft diameter, and flange code on the nameplate and datasheet (IEC 60072-1) before ordering. Do not use this page as a millimetre drawing.
Typical construction is totally enclosed fan-cooled (TEFC, IC411) with IP55 protection: dust-tight enclosure and protection against water jets.
Before you order
- kW and poles vs the installed motor nameplate
- Foot vs flange code (B3 / B5 / B35)
- Voltage and frequency (220–690 V class as specified)
- Duty S1 vs inverter supply (consider YVF2)
Same frame, other efficiency classes
JW general-purpose series use a Class F insulation system designed around Class B temperature rise, giving thermal margin in industrial ambients.
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).
Can I replace another IEC frame 71 motor with YE3 Series (IE3)?
If the installed motor is a standard IEC metric frame 71 with the same mounting and shaft, YE3 Series (IE3) is designed as a dimensional replacement. Always match kW, poles, voltage, and duty.
