significant advantages
Global Compliance & Max Efficiency
Engineered for the global marketplace, the YE3 series meets strict MEPS (Minimum Energy Performance Standards) across the EU, South America, and Asia. By optimizing magnetic flux density to drastically reduce hysteresis and eddy-current losses, we help you significantly slash facility electricity bills and achieve lower Operating Expenses (OPEX).
Seamless Drop-In Compatibility
Upgrade without modifying your infrastructure. Strictly adhering to the IEC 60072-1 metric standard, the YE3 series ensures 100% universality in shaft heights, foot mounting patterns, and flange dimensions. No baseplate remachining is required—ensuring a hassle-free, zero-threshold installation.
Premium Materials & Rugged Build
Internal Quality, External Durability. The core features W470/W600 High-Grade Cold Rolled Silicon Steel and 100% Copper Windings for superior magnetic permeability and electrical reliability. Externally, it comes standard with IP55 protection and high-load capacity bearings (SKF/NSK optional) to effectively withstand harsh operating conditions.
VFD Ready & Automation Friendly
Designed for modern automation. The motor utilizes Class F Insulation (155°C) assessed at a conservative Class B Rise (80K). This thermal reserve allows it to effortlessly handle the voltage spikes and harmonic heating associated with Variable Frequency Drives (VFDs), making it a robust choice for precision control applications.

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).
