The YE3 Series ultra-high-efficiency three-phase asynchronous motor is an energy-saving motor designed and manufactured in strict accordance with the latest national energy-efficiency standards. The series adopts a totally enclosed, fan-cooled design (IC411) and a squirrel-cage rotor structure. Its main advantage lies in its high energy efficiency. At full load, the efficiency values fully comply with the Grade 3 energy-efficiency requirements specified in GB 18613-2020, Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Small and Medium Three-Phase Asynchronous Motors. The series therefore falls within the category of energy-efficient products encouraged under national energy-saving policies.

With stable operation and reliable performance, YE3 Series motors are widely used across a broad range of industrial applications. They can serve as power sources for various types of general-purpose machinery, including metal-cutting machine tools, fluid-handling equipment such as pumps, ventilation equipment such as fans, and air compressors.

The series is also suitable for general industrial environments where flammable, explosive, or corrosive gases are not present. Typical applications include conveying equipment, mixers, printing machinery, agricultural machinery, food-processing equipment, and other production machinery. YE3 Series motors can also be used as energy-efficient replacement and upgrade options for older, higher-energy-consumption motor series such as Y and Y2.
