The design of a stator-doubly-fed doubly salient (SDFDS) machine is presented. The corresponding output power equation is analytically derived. The initial calculation of motor dimensions and parameters are also discussed. Moreover, finite element analysis of this motor is carried out, in which the interaction between the field flux and armature current flux as well as the magnetic saturation are taken into account. Hence, the characteristics of the proposed motor are deduced. A 12/8-pole SDFDS motor is designed and built for exemplification. Experimental results of the prototype are given to verify the theoretical analysis.
