Abstract:
1. A winding device for producing an electric motor field coil ( 30 ), which includes a double-layer multiple-circuit winding, said device comprising: a drive ( 40 ) configured to operate upon a winding mandrel ( 10 ) having multiple lamellas ( 11 ) arranged to be swung radially outwardly and inwardly by the drive ( 40 ) in order to produce the double-layer multiple-circuit winding as a plurality of winding stacks ( 31 a , 32 a , 33 a . . . 31 j , 32 j , 33 j ) that are arranged in separate slots and electrically connected in one of series, in parallel and both, with at least two axially-separated winding stacks ( 31 a , 32 a , 33 a ) produced at the same time by the drive ( 40 ); and a wire feed unit ( 18 ) for feeding a number of wires (u, v, w) to the winding mandrel ( 10 ) in such a way that they are swung around at least two axes (y, z), wherein the wire feed unit ( 18 ) is displaceable perpendicularly to a longitudinal axis (x) of the winding mandrel ( 10 ).
