This standard specifies the test methods for a special type of electric motor, namely an external rotor motor (hereinafter referred to as an electric motor). Its outgoing line is generally led out from a fixed axis. Electric motors can be in the form of single-phase AC, three-phase AC, DC, etc. This standard applies to external rotor motors. 2 Normative References: The clauses in the following documents become the clauses of this standard through the reference surface of this standard. For dated reference documents, all subsequent amendments (excluding corrected content) or revisions are not applicable to this standard.
