Feature and usage


    YB355-450 series of flameproof three phase asynchronous motors for conform to GB3836.1-2000 of general requirements'of flameproof electrical equipment used in explosive gas environment and GB3836.2-2000 of "d" of flameproof electrical equipment used in explosive gas environment; and suitable for the places of coal mine where there is flammable gas whichcan form explosive gas mixture with air. The flameproof marking: DI,DIIAT4,DIIBT4,DIICT4. This series of motors are mainly used in the silo of coal mine and factories with grade IIA. IIB and IIC. Protection degree is IP44 or IP54, cooling way: IC411or IC511, Class insulation: F, mounting type: IMB3,rated frequency: 50HZ, rated voltage: 6000V or 10000V.
    YB range of frame sizes500 to 800 flame-proof high-voltage medium-sized three-phase induction motors are new products, which are manufactured using the design and manufacturing techniques of explosion-proof high-voltage motors imported from Forerunners foreign company in Germany and being in combination with many years of our production experience. They have the advantages of small volume, light weight, advanced performance, small vibration, lower noise, safe and reliable operation and convenient maintenance, etc.

Oordering Informations


  1.Please indicate the motor type,rated output,rated voltage,rated frequency,synchronous speed,Explosion proof Mark,mounting type,rotation direction(view from the shaft extension side)Use of the environment(indoor or outside)If the user havn't point out the rotation and environment,normailly we think is CW roration and used indoor.

  2.when user have special requirments,For example:Dispose the stator,bearing explosion proof and bearing temperature sensors,space heater,Plateau use,specical frequency,mounting size change,special output,the user must ,order can be confirm after signing the technical agreement with engneering department .

   3.The catalogue is only fpr reference,and there may be variations.

   4.This range of motor can also be made into Variable-Frequency motors,the range of frequency of which is 0-100HZ,the output and overall dimensions should be confirm separately.
