摘要: In this paper, a double stator (DS) wound field (WF) switched flux (SF) (DS-WFSF) machine is proposed. the DS-WFSF machine, and armature windings are separately placed in two different stators. Compared with conventional WFSF single stator, which both located, nonoverlapping concentrated large slot areas can be obtained machine. The proposed exhibits >19% higher torque than machines having same space envelope being globally optimized. influence of leading design parameters, such as copper loss ratio between windings, air-gap diameter, rotor iron piece thickness widths, on average output investigated for 12/10, 12/11, 12/13, 12/14 slots/rotor pieces. All analyses confirmed by finite element experimental results.
