Description
Performance Overview
The YE4 series motors are high-efficiency, energy-saving three-phase asynchronous motors independently developed by our company. Their performance complies with GB/T 755, Rotating Electrical Machines—Rating and Performance, and JB/T 13299, Technical Specification for YE4 Series (IP55) Three-Phase Asynchronous Motors (Frame Sizes 80–400). The motors meet the Grade 2 energy efficiency requirements specified in GB 18613-2020 and correspond to the IE4 efficiency class defined in the international standard IEC 60034-30 for single-speed three-phase squirrel-cage induction motors.
Designed for efficient and reliable operation, the YE4 series offers high energy efficiency, a generous temperature-rise margin, long service life, low vibration, good starting performance, and a well-designed appearance. These motors can serve as replacements for low-voltage three-phase asynchronous motors in the Y, YGM, YGM2, YE2, and YE3 series, subject to application and installation requirements.
The YE4 series is suitable for driving a wide range of industrial equipment, including water pumps, fans, compressors, conveyors, and other transmission machinery. Its energy-saving characteristics make it a practical choice for industrial applications focused on improving energy efficiency, as well as projects involving environmental protection and water conservancy.
Application Scenarios
The high-efficiency YE4 three-phase electric motor is suitable for various industrial drive applications. Typical uses include water supply and circulation systems, ventilation equipment, air compressors, conveyor systems, and other machinery requiring dependable motor power.
When selecting a motor, users should consider the required power, operating speed, load characteristics, installation conditions, and power supply specifications to ensure that the selected model meets the needs of the intended application.
