So, choose China explosion proof motor for the safety of your equipment and property. In this guide, we will discuss different types, classifications, and applications of explosion-proof motors. So, please keep reading!

What is a China explosion proof motor? 

China explosion-proof motors are the type of motors that are specified for operating in hazardous locations. These motors have an internal explosion mechanism that prevents high-grade blasts and equipment damage. The flame proof motors are made with 100% stainless steel, copper aluminum, or cast iron to reduce the risks of friction and sparks. 

These motors prevent equipment malfunction, property damage, or in the worst scenario, severe injuries. 

Different types of explosion-proof motors:

Here are some common types of explosion proof motors that are used for different commercial and domestic applications.

Understanding the UL classification of hazardous locations is significant to find the right China explosion proof motor for your application. Let’s understand the explosion-proof motor classification;


  • Class I: It includes ignitable vapors or gas in the air, such as gasoline, acetylene, or combustible gas.
  • Class II: It includes flammable substances in the environment, such as dust particles, grains, and coal dust.
  • Class III: These locations indicate the presence of flammable fibers and flying, such as wood shavings or cotton gins. 


  • Division I: This type of location includes a commercial facility, which is hazardous even under normal conditions. These areas confirm the presence of ignition substances or gases.
  • Division II: These locations are dangerous only under an abnormal situations. For example, a sudden rupture or a burst can cause the spilling of a combustible substance.


  • Group A, B: These groups include acetylene, hydrogen, and explosive gases.
  • Group C and D: The ignition material in these groups includes gasoline, butane, and propane.
  • Group E, F & G: It includes flammable dust such as metal dust, carbon black, coke dust, starch, flour, and grains.
