The YE3-355M-4 series represents the latest generation of premium efficiency three-phase asynchronous motors, designed for industrial applications requiring reliable and energy-efficient operation. With an output power of 250KW, this motor series is particularly suitable for driving various industrial equipment including compressors, pumps, ventilators, and other general-purpose machinery.
Engineered with advanced cooling technology, the YE3-355M-4 features parallel vertical radiation ribs in its frame design and utilizes two separate cooling wind paths for optimal heat dissipation. The external fan system ensures efficient cooling while maintaining low noise levels during operation. The motor's squirrel-cage copper-bar rotor structure undergoes high-precision dynamic balance testing to minimize vibration.
This motor series offers flexible installation options with primary terminal box placement available at the top of the frame, either left or right side, or at a 45-degree angle to accommodate various application requirements. The standard mounting types include IMB3 and IMB35 configurations.
With protection classes up to IP55 and F/H insulation class (temperature rise B), the YE3-355M-4 is built to withstand demanding industrial environments. The motor operates effectively at altitudes up to 1000 meters and within ambient temperature ranges from -15°C to +40°C.
The YE3 series motors are certified with ISO9001 quality management system and CCC certification, ensuring compliance with international standards. These motors are particularly suitable for applications in hazardous areas including oil, chemical, steel plants, and mining industries where reliable performance is critical.
Customization options are available for specific voltage requirements beyond the standard 380V, 660V, 380/660V, and 660/1140V configurations. The motor's y-δ starting mode provides smooth acceleration while protecting electrical systems from excessive inrush currents.
