Multiphase alternating current dynamoelectric machine stator winding and method of disposing the winding in slots of the stator

Claim 1

IN A MULTIPHASE INDUCTION ELECTRIC MOTOR, A STATOR COMPRISING A PRIMARY CORE MEMBER HAVING END FACES, A YOKE SECTION AND A NUMBER OF TEETH SECTIONS FORMING LCOIL ACCOMMODATING SLOTS AND A BORE; A PLURALITY OF WINDING PHASES DISPLACED IN PHASE FROM ONE ANOTHER CARRIED BY SAID CORE; EACH OF SAID WINDING PHASES INCLUDING AT LEAST TWO POLE GROUPS EACH FORMED BY AT LEAST TWO COILS HAVING PREDETERMINED NUMBERS OF ELECTRICAL CONDUCTOR TURNS; SAID COILS EACH HAVING FIRST AND SECOND CONDUCTOR SIDE PORTIONS ACCOMMODATED IN SOME OF SAID SLOTS AND END TURN PORTIONS, JOINING SAID FIRST AND SECOND SIDE PORTIONS TOGETHER, PROJECTING BEYOND SAID CORE END FACES; ONE OF SAID WINDING PHASES INCLUDING ONE POLE GROUP IN WHICH THE END TURN PORTIONS THEREOF ARE ORIGINALLY POSTIONED RADIALLY NEXT TO THE BORE AND ANOTHER POLE GROUP IN WHICH THE END TURN PORTIONS THEREOF ARE ORIGINALLY POSITIONED RADIALLY NEXT TO THE YOKE SECTION; AND END TURN PORTIONS IN ALL OF THE POLE GROUPS OF AT LEAST ONE OF THE REMAINING WINDING PHASES OF SAID PLURALITY EXTENDING AT LEAST PARTIALLY BETWEEN END TURN PORTIONS OF ADJACENT POLE GROUPS, WHEREBY POTENTIAL ENGAGEMENT OF END TURN PORTIONS OF DIFFERENT POLE GROUPS ADJACENT THE BORE IS MINIMIZED.
