Patent ID: 7247962

Claim:
A stator assembly having a plurality of stator poles ( 31 - 36 ), said plurality being divisible by six, a first ( 31 ), a second ( 32 ), a third ( 33 ), a fourth ( 34 ), a fifth ( 35 ) and a sixth ( 36 ) of said stator poles being arranged successively within a predetermined angular range; three winding phases ( 70 , 72 , 74 ) connected in a delta configuration; three respective current rails (U, V, W, 38 , 40 , 42 ) associated with respective ones of said winding phases for their connection; wherein a first winding coil ( 51 ) is arranged on said first stator pole ( 31 ) and electrically connected between a first one ( 38 ) of said current rails and a second one ( 40 ) of said current rails; a second winding coil ( 52 ) is arranged on said second stator pole ( 32 ) and electrically connected between said second current rail ( 40 ) of said current rails and a third one ( 42 ) of said current rails; a third winding coil ( 53 ) is arranged on said third stator pole ( 33 ) and electrically connected between said third current rail ( 42 ) and said first current rail ( 38 ); a fourth winding coil ( 54 ) is arranged on said fourth stator pole ( 34 ) and electrically connected between said first current rail ( 38 ) and said second current rail ( 40 ); a fifth winding coil ( 55 ) is arranged on said fifth stator pole ( 35 ) and electrically connected between said second current rail ( 40 ) and said third current rail ( 42 ); and a sixth winding coil ( 56 ) is arranged on said sixth stator pole ( 36 ) and electrically connected between said third current rail ( 42 ) and said first current rail ( 38 ); wherein at least two successive winding coils ( 51 , 52 ) are continuously wound and at their interface ( 61 ) are electrically connected to an associated current rail ( 40 ) without interrupting their winding wire ( 44 ).
