GB/T 12668.901-2021 Adjustable speed electrical power drive systems—Part 9-1:Ecodesign for power drive systems,motor starters,power electronics and their driven applications—General requirements for setting energy efficiency standards for power driven equipment using the extended product approach (EPA) and semi analytic model (SAM)
Abstract
This part of GB/T 12668 specifies the general method for energy efficiency standards for all extended products that use the extended product method (EPA).
The committee for the drive equipment of motor systems (referred to as extended products) can calculate the system energy efficiency of the entire application by the relative loss of the connected motor system (e.g., electric drive system).
The system energy efficiency is calculated based on specific models such as the speed/load curve, the working mode, and the relative loss at the corresponding torque-speed operating point.
This part specifies the method for calculating the loss of extended products and their components.
This part applies to motor systems controlled by motor starters or converters [electric drive systems (PDS)].
This part does not explicitly propose requirements for environmental impact statements.
