What type of motor is explosion proof
Every year, more than 5000 workers receive serious injuries due to fire or explosions at the workplace. Most of these mishaps occur due to faulty machinery and equipment malfunction. This happens because internal parts of machinery get heated up after working continuously, thus, increasing the risks of sparks at the work site.
Explosion proof electric motors are designed to tackle the issue of explosions in most commercial appliances. These motors have become a popular choice for industrial machinery because of their outstanding safety features. Xinnuo Motor is one of the top electric motor manufacturers in China that supplies high-grade explosion-proof electric motors.
Are you wondering what type of motor is explosion proof? This article will help you to understand the classification, specifications, and selection guide for explosion-proof motors. Let’s take a look!
What type of motor is explosion proof?
An electric motor having an internal explosion that prevents the explosion from spreading in the commercial setting is called an explosion-proof motor. These motors maintain an internal temperature less than the flammable material to avoid large blasts. The explosion-proof motors are manufactured with high-grade steel and strong housing to ensure safety in the workplace.

Explosion-proof Electric Motor
Explosion-proof motors are a significant type of industrial motor that reduces the risks of a massive explosion in hazardous areas. These motors tend to reduce overheating in the internal parts to provide maximum safety.
Explosion-proof motors are available in both single-phase and three-phase winding. However, the application range of both motors is different. Single phase explosion proof motors are used for low-grade commercial purposes, and three phase explosion-proof motors are applicable in high-grade industrial equipment.

Explosion proof motor classification:
If the question “what type of motor is explosion proof?” is still coming up in your mind, let’s simplify it further!
Not all types of explosion proof electric motors are valuable for all hazardous locations. Explosion-proof motors are classified according to the hazardous application. Let’s closely understand the classification of explosion-proof motors with the help of table.
|Division I location is the most hazardous location as it indicates the presence of flammable agents during normal motor operation.||Division II is only hazardous under certain abnormal circumstances such as rupture, malfunction, leak, or spill.|
|Examples: Ignition liquid and vapors||Examples: flammable gas and vapors|
|Class I contain flammable vapors in the air.||Class II type contains combustible solid material in the environment.||Class III type indicates the presence of ignitable fibers nearby.|
|Acetone, gasoline, ethylene||Dust, grain, coil, and debris||Flour, wood shaving, and fibers.|
|Group C and D contain ignition gases such as hydrogen, acetylene, diethyl ether, ethane, methane, styrene, and ammonia.||Group F and G consist of flammable particles such as wheat, corn, nylon fibers, polythene, and wheat flour.|

Selecting the appropriate explosion proof motor according to your hazardous application:
After understanding, what type of motor is explosion proof? It is very significant to grasp the selection criteria of explosion-proof motors to find the right fit for your application. Let’s discuss some common factors to consider while choosing a suitable explosion-proof motor;
- Closely identify your hazardous location to find the right fit.
- Research the market and company’s background.
- Analyze the Divisions, Classes, and Groups, and be sure where your location lies for accessible installation.
- If your location is Div I and Class I, you must choose a high-grade explosion-proof motor.
- If your location is Div II and Class II, choose a reliable motor with robust housing and temperature regulation feature.
