There are many manufacturing techniques where the magnets can be either on the stator or on the rotor, and can be made of different materials such as ferrite, plastoferrite, etc. Present production is with 48-Volt D.C. motors, 100 - 300 Watt output on the shaft, speed 1500 ÷ 2500 rpm.
Brushless motors are used for coupling with centrifugal and axial fans.
