Design considerations for the brushless doubly‐fed (induction) machine [PDF]
A design procedure for the brushless doubly‐fed machine is based on equations derived from a simplified equivalent circuit. The method allows the many variables in the design of this machine to be handled in a straightforward way. Relationships are given for the division of slot area between the two stator windings and for the design of the magnetic ...

High-Performance Ferrite Permanent Magnet Brushless Machines [PDF]
The performance of a brushless permanent magnet machine topology equipped with axially and circumferentially magnetized ferrite permanent magnets is presented. Simulation studies show that for smaller ratios of axial length to active length, air-gap flux densities in excess of 1 T can be achieved, resulting in significant improvements in torque ...
