摘要
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 circuit. The design method is applied to a frame size 180 machine. In particular, calculated values for flux densities in the machine have been verified by time stepping finite element analysis for actual operating conditions. The approach outlined can also be used as part of a design optimisation routine.
