Mining motor
Explosion-proof function is conformed to the standard and regulation of GB3836.1-2000<the first part of the electrical equipment in the explosive gas atmospheres: Universal requirement and GB3836.2-2000<the second part of the electrical equipment in the explosive gas atmospheres: Explosion-prood "d" type>. It is applicable to the non-mining coal mine job and factory contains an explosive mixture of the workplace.
YB2 series motors are totally enclosed self-fan-cooling three-phase asynchronous squirrel-cage type Explosion-proof motors, are designed by a nationally unified basic series of explosion-proof motor. YB2 is replacement of YB Series Motor Products. It has advantages of high efficiency, energy saving, temperature margin, long life, the good, high protective degree, low noise, small vibration, safe and reliable operation, small size, light weight, pleasing in appearance, easy to use and maintain

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.
