This study presents investigations on different winding designs for dual three-phase permanent magnet synchronous machines. Dual three-phase machine design can enable a reduction of the maximum IGBT current by increasing the number of phase belts from three to six. Dual three-phase machines have important advantages compared to conventional three-phase machines such as decreased torque pulsation and increased fault tolerance. In this contribution a short pitch dual three-phase winding where the winding sets are placed in seperate halves of the stator with no-phase shift between the two subsystems is compared to a dual three-phase winding with thirty degree phase shift between the two winding subsystems. This paper presents 2D finite-element analysis of the different winding designs and provides acoustic measurements to verify the conclusions.
