The requirements for measuring the energy efficiency of motors powered by non-sine waves are formulated by IEC /TC2 and published in the IEC 60034 series. IEC /SC22G also has a standardization working group on energy efficiency. This working group works closely with several other technical committees (e.g., IEC /TC2, IEC /SC121A). IEC /SC22G is responsible for the energy efficiency and ecological design of power electronics, switchgear, control devices, and variable speed drive systems and their industrial applications All relevant aspects of the field. The core requirements of energy efficiency standardization are shown in Figure 1.Take the proposed reasonable goals as the best compromise plan for all relevant parties. Figure 1 Examples of core requirements for energy efficiency standards All parts of GB/T 12668 do not involve mechanical engineering components. Note. Gear motors (motors with directly adapted gearboxes) are regarded as electric drive systems (converter plus motor). For the classification of gear motor losses, see See IEC 60034-30-1.The efficiency level of the gearbox as a separate component is under consideration. Each part is published in the form of national standards, some of which have already been published. Other parts will be released one after another, the following footnotes and figures (For example.

Adjustable Speed Electric Drive System Part 9-2.Electric Drive System, motor starter, power electronic equipment and its drive Applied eco-design electric drive system and motor Energy efficiency index of starter1 ScopeThis part of GB/T 12668 specifies the complete drive module (CDM), electrical drive system (PDS) and motor starter for power electronic equipment. The energy efficiency index of the actuator and all the equipment to be transmitted. This section specifies the loss determination method of the complete drive module (CDM), electrical drive system (PDS) and motor system. This section defines the IE/IES levels and their limits of the motor system, and provides the corresponding test steps for the motor system Classification of overall loss. In addition, this part proposes a realization method of the best energy efficiency solution for the transmission system. The method relies on the motor drive system The structure, speed/load relationship curve and the operating point of the driven equipment over time. GB/T 12668.901-2021 defines the extended product method and the semi-analytical model.
