Explosion-Proof Motors for Underground Coal Mines

Baldor Electric Company (a member of the ABB group) provides totally-enclosed explosion-proof motors for use in the dust-filled explosive atmosphere of underground coal mines.

In the continuous (24/7) operation of underground coal mines around the world, rugged and durable motors are required to power the constantly-running mining machinery. These motors need to be maintenance-free and must be designed to operate safely and efficiently in this hazardous and severe environment.

Baldor Electric’s totally-enclosed explosion-proof motors are designed for use in the dust-filled explosive atmosphere of an underground coal mine. Tight machining tolerances of the housings, bearing brackets, and the conduit box provide the explosion-proof integrity required by MSHA and other international certifying agencies. Cast iron conduit box parts along with packing glands and protective hose connectors meet the requirements of ATEX, IEC and MSHA and other certifying agencies.
