Explosion-proof  motor is a kind of motor which can be used in flammable and explosive  place, and does not produce electric spark during operation. Explosion-proof motor is mainly used for coal, oil and gas, petrochemical and chemical industry. In  addition, in the textile, metallurgy, city gas, transportation, grain  and oil processing, paper, medicine and other departments are also  widely used. Explosion-proof motors as the main power equipment, usually used  to drive pumps, fans, compressors and other transmission machinery.
      Explosion - proof motor and ordinary motor difference
Explosion-proof motor and ordinary motor difference:
1, explosion-proof motor is generally used in flammable and explosive situations.
2, explosion-proof motor junction box seal better than ordinary motor.
3, explosion-proof motor protection level minimum IP55, and ordinary  motor IPIP23, IP44, IP54, IP55, IP56 range, so from the shape can be  resolved.
4, explosion-proof motor is a flammable and explosive factory can be used in a motor, running does not produce spark.
5, explosion-proof motor is mainly used for coal, oil and gas, petrochemical and chemical industry. In addition, in the textile, metallurgy, city gas, transportation,  grain and oil processing, paper, medicine and other departments are also  widely used.
6,  explosion-proof motor as the main power equipment, usually used to  drive pumps, fans, compressors and other transmission machinery.

     The working principle and characteristics of explosion - proof motor
      The  explosion-proof motor uses a flameproof enclosure to separate the  electrical parts that may generate sparks, arcs, and dangerous  temperatures from the surrounding explosive gas mixture. However,  this housing is not sealed, and the surrounding explosive gas mixture  can enter the inside of the motor through the joint surface clearance of  the various parts of the housing. When  the fire with the shell, the arc, dangerous high temperature and other  ignition sources may explode, when the motor explosion-proof shell will  not only damage or deformation, and the explosion of flame or hot gas  through the joint surface gap, Nor can it ignite the surrounding explosive gas mixture.
YBX3 explosion-proof motor not only explosion-proof this feature, there are other significant features:
(1) power level, installation size and speed of the corresponding  relationship with the general Y series motor, taking into account the  inheritance with the YB series and Y2 series interchangeability, made  the necessary adjustments, more effective and applicable.
(2) YBX3 full range of use F-class insulation, temperature rise by B-level assessment.
(3) noise limit than the YB series is low, close to the YB series I level noise, vibration limit and YB series quite.
(4) enclosure protection level increased to IP55.
(5) YBX3 full range of low noise deep groove ball bearings, base height of more than 180mm motor set injection device.
(6)  motor heat sink has a parallel horizontal distribution and radiation  distribution of two, mainly parallel to the horizontal distribution.
