YZR. YZ SERIES THREE-PHASE ASYNCHRONOUS MOTORS FOR LIFTING AND METALLURGICAL PURPOSES

YZR and Yz series three-phase asynchronous motors are specialized motors for various types of metallurgical, liftingmachinery, and other similar equipment. They have high overload capacity and mechanical strength, and are suitable foifreauent starting, braking, and eguipment with significant vibration and impact under short-term or intermitent periodicworking conditions, The power level and installation dimensions of the motor comply with lEC promotion standards, similalto japan's jEM1202 and West Germany's DiN42681, and most of them are interchangeable. The motor can ensure normaoperation at an altitude of no more than 1000 meters. The insulation level of electric motors can be divided into two types: Flevel and H level: F level is suitable for general places with ambient air temperature not exceeding 40 c; Class H is suitablefor metallurgical sites with an ambient air temperature not exceeding 60 'c. Both types of motors have the same parametersThe protection level used in general places is iP44, and the protection level used in metallurgical places is lP54.The rated frequency of the motor is 50Hz and the rated voltage is 380V. The YzR series is a wound rotor motor thatmeets the JB/T10105-1999 standard, while the YZ series is a sauirrel cage rotor motor that meets the JB/T10104-1999standard.
