Electric motors are an integral part of the mining industry. Historically, the mining business used mostly DC motors. Over time, those motors have been replaced with AC motors. Likewise drive systems are evolving from fixed to variable speed. Similar to AC motors taking over DC motors, the mining business is seeing a move from induction motors to synchronous motors on the surface.

At EMX, we understand these trends in your industry and work with companies like you to identify your critical equipment, maintenance and reliability needs.
