Explosion-proof motors are specifically designed to reduce the risk of explosions in environments that contain flammable gases, vapors, dust or fibers. Regardless of the environment, electric motors generate heat when they operate which can create an ignition source in certain dangerous situations. The problem occurs when the case temperature of a conventional electric motor exceeds its autoignition temperature (AIT). In the worst cases, this could spark incendiary dust or vapor that has accumulated in the factory environment to start a fire or explosion. To prevent these catastrophic accidents, explosion-proof motors are made in a specialized manner to ensure that any internal fire or explosion won't spread throughout the commercial, industrial facility and trigger an even larger incident.

Aside from being built in a specialized way to prevent accidental fires and explosions, these motors are also certified to meet specific safety regulations imposed by UL, ATEX or CSA. These certifications are based on the class, division and group classification of the environment in which the motor will operate.

Understanding how these classifications work can help you select the right electric motor for your hazardous location applications. We also stock explosion-proof motors that can handle the conditions of Class II, Division 1 environments where there's a medium probability of combustible dust or fiber present.

Identifying the class, division and group classification of your hazardous environment can be done by consulting with the safety regulatory authority in your region or country. After you've correctly identified your hazardous location, selecting the right electric motor for the job will be simple.

Explosion-proof motors feature thick, hardened housings that are resistant to external shocks and pressure. They also have flame paths that allow hot gases to escape from the casing in a controlled manner and cool down to safe temperatures before they ignite flammable materials on the shop floor.

In addition to the flame paths, these motors are fitted with extra-low wattage windings and sealed bearings that reduce the chances of an external ignition source sparking in the motor's case. The specialized design also allows for easy maintenance in hazardous locations, making them ideal for industrial and manufacturing facilities.

Our service-minded team is here to help you every step of the way and will find the perfect motor for your needs. We can help you get the right equipment in place that will improve productivity without posing any significant danger to your employees or the environment.
