Patent ID: 8035263

Claim:
An electric motor comprising a rotor ( 52 ) rotatable around a rotation axis ( 56 ); a stator ( 60 ) arranged around said rotor ( 52 ), which stator is equipped with poles ( 11 ′ to 16 ′) on each of which is implemented an individual winding ( 11 to 16 ), which individual windings are wound from wire and together form a winding arrangement ( 30 ) that serves to generate a rotating field, the wire having at least one connecting wire section between one individual winding and another individual winding, in the manner of a continuous winding arrangement, furthermore comprising at least one arrangement, arranged approximately concentrically with the rotation axis ( 56 ), having electrical connection elements (U, V, W, U′, V′, W′) that are equipped with mounting elements ( 34 , V 1 , W 1 , U′ 1 , V′ 1 , 32 , 36 ) to each of which connection elements (U,V,W, U′, V′, W′) two associated individual windings are mechanically and electrically connected, at least some of the connections being between a mounting element ( 34 , V 1 , W 1 , U′ 1 , V′ 1 ) and a connecting wire section; and a connection arrangement ( 40 ) including a ring ( 100 , 140 ) of insulating material into which conductors ( 42 , 44 , 46 ) are embedded, and in which conductive elements project outward from the conductors ( 42 , 44 , 46 ), which conductive elements are configured at their free ends ( 102 , 106 , 108 , 110 , 112 , 116 ) for a welded connection to an associated connection element (U, V, W, U′, V′, W′), a free end of each of which is connected, by means of a welded connection ( 155 ), to connection elements of the stator that are associated with said conductive elements, in order to electrically interconnect said connection elements, associated with said conductors, in a predetermined fashion; and wherein the outwardly projecting conductive elements are each bent over adjacent their respective free ends, the bent-over part extending substantially parallel to the portion of the associated connection element to which said bent-over part is welded.
