Design considerations for the brushless doubly‐fed (induction) machine [PDF]
IET Electric Power Applications, 2016 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 ...
