Scope

This part of GB/T12668 specifies the energy efficiency indicators of power electronic equipment complete drive module (CDM), electric drive system (PDS), motor starter and all driven equipment. This part specifies the loss determination method of complete drive module (CDM), electrical drive system (PDS) and motor system. This section defines the IE/IES level of the motor system and their limits, and provides the corresponding test steps for the classification of the overall loss of the motor system. In addition, this section presents a method to realize the optimal energy efficiency solution of the transmission system. The method relies on the architecture of the motor drive system, the speed/load relationship curve and the operating point of the driven equipment over time. GB/T12668.901—2021 defines the extended product method and semi-analytical model. The structure of this part is as follows: ---Give the loss of the standardized reference electric drive system (RPDS) and the standardized reference complete drive module (RCDM), establish a mathematical model to calculate the loss, and classify it; ---Define the reference motor (RM) and reference complete drive module (RCDM), and are used to determine the IE level of the entire motor system when a certain component of the motor system is unknown; --- Give the determination of the actual electrical drive system (PDS) and the actual complete drive module (CDM) loss requirements, and compared with the reference electric drive system (RPDS) and the reference complete drive module (RCDM); --- Give the requirements for type tests and user documentation; --- The appendix explains some of the whole system with examples Loss; --- The appendix gives information about the system and drive topology. For single-shaft AC/AC electric drive systems with low-voltage (100V~1000V) three-phase motors, this section gives the losses and IE of the reference complete drive module (RCDM), reference motor (RM), and reference electric drive system (RPDS). /IES-level specific values. A geared motor is considered a standard motor when the motor and gearbox can be separated. All reference data provided are from electric drive systems (PDS) with induction motors. It can be used in all electrical drive systems (PDS) with other types of motors. The application of this part to the following equipment should be technically feasible, but not mandatory: --- High voltage complete drive module (CDM) and electric drive system (PDS) with AC rated voltage higher than 1000V; --- - low-voltage complete drive module (CDM) and electric drive system (PDS) with AC rated voltage lower than 100V; - high-power electric drive system (PDS) with rated power higher than 1000kW; - rated output apparent power High-power complete transmission module (CDM) higher than 1209kVA; ---low-power electric drive system (PDS) with rated power lower than 0.12kW; ---low-power complete transmission module with rated power lower than 0.278kVA (
