In order to better guide consumers to use high-efficiency motors, our country adopts energy efficiency label management for basic series motors. Such motors should be registered on the China Energy Efficiency Label Network and the corresponding energy efficiency logo should be affixed to the motor body.
Taking the more commonly used YE2, YE3, YE4 and YE5 motors as an example, the same energy efficiency may not be an energy-saving motor in different periods. To determine whether the motor is an energy-saving motor, it must correspond to the GB18613 standard valid at the time. The energy efficiency of the motor is divided into 3 levels, level 1 is the highest level, and level 3 is the energy efficiency requirement that the motor must meet, that is, the minimum limit value requirement, that is, the efficiency level of this type of motor is not lower than the limit value requirement before it can enter the market for sale.
Are all motors with energy efficiency labels affixed high-efficiency motors?
The answer is no. Motors within the scope of energy efficiency label management must be registered on the China Energy Efficiency Label Network and affixed with their exclusive energy efficiency labels (with QR codes) before they can enter the market. According to the standard, motors with level 3 energy efficiency labels are not energy-saving products, while motors with level 2 or level 1 energy efficiency labels are energy-saving products.
What are the energy-saving motors corresponding to different versions of the standard?
At present, the effective version of the GB18613 standard is the 2020 version. Under this standard, the YE3 series motors are only motors that are allowed to be produced. Their efficiency level corresponds to the IE3 level of the international standard, and the product energy efficiency label is level 3 energy efficiency. The efficiency levels of the YE4 and YE5 series motors correspond to IE4 and IE5 respectively, and the energy efficiency labels correspond to level 2 and level 1 respectively, which are energy-saving motors. In the 2012 version of GB18613 that has been replaced, the energy efficiency of the YE2 series motors is a limited value, and both YE3 and YE4 are energy-saving motors. As this version of the standard is replaced, its corresponding energy efficiency level has also been repositioned.
Therefore, consumers of motors should have this knowledge in order to better control the relevant requirements in the motor procurement process. Many motor manufacturers have passed third-party energy-saving certification to prove the energy efficiency advantages of their products. Consumers should identify the effectiveness of the energy-saving certification they provide and be clear consumers.
