GB 30253-2024
ActiveMinimum allowable values of energy efficiency and energy efficiency grades for permanent magnet synchronous motors
永磁同步电动机能效限定值及能效等级
Application Summary AI generated
This standard specifies the minimum allowable values of energy efficiency and the energy efficiency grades for permanent magnet synchronous motors. It is applied in China to classify motors from Grade 1 (highest efficiency) to Grade 3 (lowest allowable efficiency), serving as a regulatory benchmark for manufacturing, procurement, and energy audits in industrial applications such as pumps, fans, compressors, and electric vehicles. Compliance ensures that motors meet mandatory energy conservation requirements under China’s energy efficiency labeling system.
