Patent ID: 7521835

Claim:
A permanent magnet machine, comprising: at least one permanent magnet rotor comprising an inner rotor component and an outer rotor component; at least one stator positioned between the inner rotor component and the outer rotor component, the stator comprising inner slots adjacent the inner rotor component and outer slots adjacent the outer rotor component; a plurality of polyphase inner windings associated with the inner slots, wherein at least one inner winding includes a first inner strand and a second inner strand, wherein the first inner strand is closer to the inner rotor component than the second inner strand, a plurality of polyphase outer windings associated with the outer slots, wherein at least one outer winding includes a first outer strand and a second outer strand, wherein the first outer strand is closer to the outer rotor component than the second outer strand, wherein the first inner strand is connected to the second outer strand at a first connection, and wherein the second inner strand is connected to the first outer strand at a second connection, and wherein the first and second connections provide transposition between the at least one inner winding and the at least one outer winding.
