The metal industry requires electric motors that can withstand high temperature, high starting torque, and vibration, also and have overload capabilities. Another concern in the metals factory is the amount of metal dust and debris that can accumulate in the motor fins impacting motor performance and cooling capabilities. The most common applications are hot and cold rolling mills, blast furnace blowers, cooling pumps, sinter fans and blowers.
PM motor applications are also found in the metals industry, particularly using low speed high torque designs which allow the reduction in size of electric drives and removal, or reduction in the size of
mechanical gear systems.
