【Abstract】 This paper presents the design and analysis of the stator-doubly-fed doubly salient (SDFDS) motor for electric vehicles. A sizing equation is derived, which lay a foundation for the initial design of the machine. A 3-phase 12/8-pole SDFDS motor is designed and built for exemplification. Moreover, finite element analysis for the machine is carried out to investigate field distribution, back EMF, inductance characteristics and static torque. In the analysis, the interaction between the field flux and armature current as well as the magnetic saturation are taken into account. Experimental results of the prototype machine are given to verify the theoretical analysis, which are helpful on further studying the SDFDS motor and designing the drive system.更多还原
