Scope: It specifies the classification and naming, requirements, other requirements, test and inspection methods, inspection rules, and marking, packaging, transportation, and storage of high-power EC permanent magnet synchronous external rotor intelligent centrifugal fans (hereinafter referred to as fans). It applies to external rotor centrifugal fans driven by electronic commutation permanent magnet synchronous three-phase motors with an input power of more than 3 kW and less than 15 kW; Main technical content: The standard specifies the scope of application of high-power EC permanent magnet synchronous external rotor intelligent centrifugal fans, normative reference documents, terms, and test contents and methods, including the temperature rise limit values of the drive shell and modules, the energy efficiency, intelligence, reliability, and environmental protection requirements of the whole machine in terms of manufacturing and performance. It is applicable to the optimization of high-power EC permanent magnet synchronous external rotor intelligent centrifugal fans. The standard describes each level and stipulates the corresponding functional and performance indicators required for each level.
