In some ways, high energy prices are not all bad. This is especially true when global power demand and the price of copper push engineers to develop new energy efficient motor control technologies. While AC motor use dominates most applications, it isn't efficient at variable speeds. Permanent magnet motors have been available for years, but they have been expensive and require complicated control methods. Now the good news; advances in low cost sensorless PM control technology are widening the use of these motors while reducing power consumption. Does this strategy make sense for your process?
