U mutore elettricu di China hè partutu da l'efficienza IE3 da u 1u di ghjugnu 2021
The national standard GB18613-2020 was announced, and the electric motor industry will fully enter the "IE3 high efficiency era" from June 1, 2021
For GB18613-2012, the new version of the standard deletes the target energy efficiency limit value of the motor and the motor energy saving evaluation value, raises the requirement for the energy efficiency limit value of the three-phase asynchronous motor, and adds the energy efficiency level of the 8-pole three-phase asynchronous motor; for the GB25958-2010, the new version of the standard The energy efficiency index requirements for capacitor start, capacitor operation, and dual-value capacitor asynchronous motors have been improved. The energy efficiency index requirements for room air conditioner fan motors have been deleted. The energy efficiency index requirements for capacitor running motors for air conditioner fans and brushless DC motors for air conditioner fans have been added. , Deleted the 120W energy efficiency rating requirements for single-phase and three-phase low-power motors, and deleted the technical requirements for target limit values and energy-saving evaluation values for low-power motors. The standard is scheduled to be implemented on June 1, 2021, which means that by then energy efficiency motors below IE3 will be forced to stop production, and the domestic motor industry will fully enter the "IE3 high efficiency era"
