Abstract:
A stator for an electrical machine, comprising a hollow-cylindrical yoke, a plurality of poles protruding inward from said yoke and extending over an axial length of said yoke; an exciter winding including a plurality of windings which are wrapped around each of said poles so as to alternatingly incompass each of said poles on axially each of said poles on axially outwardly pointing face ends of said poles facing away from one another and so as to extend between said poles along an inner wall of said yoke, each of said windings of said exciter winding being a bundle conductor which includes a plurality of parallel-wound round wires located side by side on said face ends of each of said poles, said poles including a first plurality of poles which are connected permanently to said yoke and a second plurality of poles which are detachably connected to said yoke, said poles of said first plurality and said poles of said second plurality alternating with one another, said poles being assembled as a packet, each of said poles having a pole core which contacts said yoke and a pole shoe provided on a free end of said pole core, said pole core having an end which is remote from said pole shoe, said yoke being provided with axial shoe guides, said detachable poles being formed as insertable poles which are form-lockingly inserted in said axial shoe guides in an axial direction, said inner wall of said yoke being flattened across a tangential width of said pole core of said detachable poles such that said pole core rests flatly on said inner wall of said yoke.
