In this introductory article, we will study the working mechanism, advantages, and applications of explosion-proof 3 phase motors. 

Working of explosion proof 3 phase motor:

Explosion proof 3 phase asynchronous motors have an internal combustion system that prevents the motor from immense blasts if a spark ignites in the motor. The explosion-proof motor keeps its external temperature below the explosive gas, vapors, or dust particles. Technicians have designed different explosion-proof motors for various hazardous materials and zones. Major Classes and groups of explosion proof asynchronous motors are discussed below; 


  • Class I: flammable liquid, gases, and vapors.
  • Class II: dust and debris particles
  • Class III: combustible fibers, flings, and threats


  • Group C: Ethyl ether, cyclopropane, ethylene. 
  • Group D: Acetone, alcohol, benzene, butane, etc.  
  • Group F: Charcoal, coal, coke dust
  • Group G: Grain, combustible dust, and flour

A user must select the right explosion proof 3 phase motor asynchronous motor that is designed for their application to ensure safety at the working location.

Advantages of three phase asynchronous motors:

Following are some remarkable advantages of 3 phase explosion proof motors;

  • High-efficiency and power output
  • Maximum rpm and torque production
  • Internal/external protection
Applications of explosion proof 3 phase motors:

3 phase explosion proof motors are widely used in industries that demand high efficiency and protection. Industrial operations that involve heat, electrical sparks, and fire implement explosion-proof motors to save working sites from damage or mishaps.

You can find explosion-proof motors in the following industries;

  • Petroleum/oil refinery 
  • Pharmaceutical production industry
  • Mining industries
  • Blowers, Pumps, and fans manufacturing industries 
  • Gas Extraction industry
  • Chemical industry 

Xinnuo Motor offers a wide range of industrial motors, OEM motors, and 3-phase electric motors. 


Explosion proof 3 phase asynchronous motors not only provide protection but also ensure efficient performance of electric motor in machinery equipment. These motors contain an internal explosion, which protects the entire working facility from a hazardous situation. For further inquiries and quotation services, contact us
