YE3 Three-Phase Asynchronous Motor

The YE3 Series High-Efficiency Three-Phase Asynchronous Motors are independently designed and manufactured by our company to meet the growing demand for energy-saving industrial drive solutions. The motors comply with GB/T 28575 Technical Conditions for YE3 Series (IP55) Three-Phase Asynchronous Motors (Frame Sizes 63–355) and JB/T 10868 Technical Conditions for YE3 Series (IP55) Three-Phase Asynchronous Motors (Frame Sizes 355–400).

The efficiency ratings satisfy the Grade 3 energy efficiency requirements of GB18613-2020 and are fully aligned with the IE3 efficiency class specified in IEC 60034-30, the international standard for single-speed three-phase squirrel-cage induction motors.

Designed for reliable and economical operation, the YE3 series offers excellent electrical and mechanical performance with outstanding energy efficiency. These motors feature a generous temperature rise margin, extended service life, low vibration, smooth starting performance, and dependable long-term operation. Their optimized structure and modern appearance allow them to directly replace traditional Y, YGM, YGM2, and YE2 series low-voltage three-phase asynchronous motors without requiring major system modifications.

The YE3 series is widely used to drive a variety of industrial equipment, including:

• Water pumps

• Industrial fans

• Air compressors

• Conveyor systems

• General machinery

• Production equipment

They are extensively applied in industrial automation, energy-saving upgrades, environmental protection projects, municipal engineering, and national water conservancy infrastructure.
