Design of a Fractional Slot Concentrated Winding Double-Speed AFPM Motor
In this paper, a new topology of fractional slot concentrated winding double rotor axial flux permanent magnet synchronous motor (FSCW-DRAFPMSM) is introduced.The desired structure consists of a nonslotted stator core and two rotor discs.The pole number of the two rotors is different and these two rotors Christmas Village rotate at different speeds
