This standard specifies the general safety requirements for small and medium-sized rotating motors (motors and generators, hereinafter referred to as motors) for general purposes. This standard is applicable to general purpose small and medium-sized rotating motors. For low-power motors produced according to GB/T 5171, GB 12350 can also be used as the assessment basis. The general safety requirements for other types of motors can be referred to for use. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document.
