According to GB 18613-2020 “Minimum Allowable Values and Energy Efficiency Grades for Electric Motors,” motor efficiency is commonly classified into four levels.
Efficiency ≥ 92%
High-efficiency motors provide excellent energy-saving performance and are suitable for industrial systems with strict energy consumption requirements.
Efficiency between 88% and 92%
Suitable for standard industrial machinery and general-purpose equipment.
Efficiency between 84% and 88%
Applicable to equipment with relatively lower performance requirements.
Efficiency ＜ 84%
These motors consume more electricity and are gradually being phased out in many industries.

According to IEC 60034-30-1, motor efficiency classes are divided into:
IE1
IE2
IE3
IE4
IE5
Among them, IE5 motors represent ultra-premium efficiency technology, providing significantly lower power consumption and improved operating economy.

The motor and driven equipment should normally be connected through a coupling for coaxial transmission. If belt drive, chain drive, or gear transmission is required, please specify before ordering.
Variable frequency motors are recommended to operate with a VFD. Please inform us in advance if special starting methods are required.
Chinese-brand bearings are standard. If SKF, NSK, FAG, or other imported bearings are required, please specify before ordering.
Standard motor design is suitable for locations below 1000 meters altitude. For high-altitude environments, customized design may be required.
Standard operating ambient temperature range is -15℃ to +40℃. For extreme temperature environments, please provide detailed operating conditions before ordering.
