YE4 High-efficiency series motors

Performance Overview

The YE4 series electric motor is a high-efficiency, energy-saving three-phase asynchronous motor independently developed by our company. Its performance complies with the standards GB/T 755 ("Rotating electrical machines – Rating and performance") and JB/T 13299 ("Technical specifications for YE4 series (IP55) three-phase asynchronous motors, frame sizes 80–400"). The efficiency values meet the Grade 2 energy efficiency standard specified in GB 18613-2020 and align with the IE4 class defined in the international standard IEC 60034-30 ("Efficiency classes of single-speed, three-phase, cage-induction motors").

This series of motors offers outstanding performance, high efficiency, energy savings, a large temperature rise margin, long service life, low vibration, excellent starting characteristics, an attractive appearance, and high reliability. They can fully replace YGM, YGM2, YE2, and YE3 series low-voltage three-phase asynchronous motors. They are commonly used to drive water pumps, fans, compressors, conveyors, and other transmission machinery, and are widely applied in projects such as energy-saving and environmental upgrades and national water conservancy initiatives.
