Explosion-proof motors
Explosion-proof motors are specially designed electric motors that are used in potentially explosive environments. Such environments are often found in the gas, oil and chemical industries, in the Mining as well as in areas where flammable gases, vapors or dust can occur.
Purpose of explosion-proof motors
The primary purpose of an explosion-proof motor is to minimize the risk of an explosion by preventing hot surfaces or electrical sparks from coming into contact with the surrounding explosive atmosphere. Various protection methods are used for this purpose.
