Brushless PM-Motors Speed Ahead - June 2014
The article "Brushless PM-Motors Speed Ahead" appeared in the June 2014 issue of Power Transmission Engineering.
There are more brushless PM motors being made every day. These brushless PM motors are smaller in size -- i.e., less than 50 watts in power output found in hard-disk drives, CD and DVD players and many portable medical devices. Servo systems with brushless PM motors ranging from 50 watts to 50 kilowatts are now challenging the larger electric motor applications. A few manufacturers have pushed brushless PM motors above 200 kW.
