三相异步电动机的型号(国外英文资料) Type and selection of three-phase asynchronous motor The classification of three-phase asynchronous motor Three-phase asynchronous electric general for the series, the series, varieties and specifications, so the classification is various. 1, according to the motor size classification Large diameter: D, motor stator core 1000mm or shaft center height H 630mm. Medium sized motor: D=500~1000mm or H=355~630mm. Large motor: D=120~500mm or H=80~315mm. 2, according to the classification of motor shell protection structure 3, according to the classification of motor cooling The motor according to the cooling mode can be divided into self cooling and self cooling fan and fan cooled him etc. 4, according to the classification of motor mounting form IMB3: horizontal, frame with feet, endshield without flange. IMB5: horizontal, frame without foot, end cover flange. IMB35: horizontal, frame with foot, end cover flange. 5, according to the operation of the motor work classification S1; continuous working system S2: short-time working system S3~S8: periodic working system 6, according to the classification of the rotor structure Three-phase squirrel cage asynchronous motor Type and selection of three-phase winding asynchronous motor of three-phase asynchronous motor Preparation method of Chinas motor product model is carried out in accordance with the national standard GB4831-84 motor model establishment method, namely the Chinese phonetic alphabet and international symbol and Arabia numbers, according to the following order. 1 product code (type) CHANPINGUI synchronous motor asynchronous motor synchronous generator DC motor DC generator turbine generator turbine generator dynamometer submersible pump motor commutator motor used in textile T TF Z ZF product code Y QF SF C Q F H The 2 code of special environment Use tropical wet tropical dry plateau with marine chemical corrosion by external users The Chinese phonetic alphabet, T TH TA G H W F Product specifica
