National standards with international standardsNational standards (code GB): General requirements and technical requirements; motor GB755-65 motor basic technical requirements: the requirements of all types of motor technology, nameplates, line-side flag; GB760-65 motor mounting dimensions and dimensions of the Code require the installation of all types of motor and shape size Code. Ministerial standard (Code JB): The technical requirements of the particular type of motor rated data, conditions of use; JB742-66 J2 the JO2 series three-phase asynchronous motor technical conditions; JB1104-68 Z2 series of small DC motor technology conditions. Various types of motor test methods: GB1032-68 small and medium-sized three-phase asynchronous motor test. International standards: Refers to the relevant standards established by the International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC). IEC Technical Committee (TC2) is specifically formulated rotary motor standard bodies, it has six sub-technical committee, in charge of the turbine generator, size, and power levels, brush, brush holders, commutators and collector ring, test methods and procedures, shell protection, cooling and installation as well as motor insulation classification. |
