Abstract:
An electrical coil winding assembly for a rotating electrical machine comprising a core assembly, said core assembly being formed by annular, radially inner and radially outer elements, at least one of said core elements forming a plurality of circumferentially spaced, armature cores extending radially from one of said radially inner and radially outer elements, electrical coils wound around said armature cores, a plurality of bobbins, each surrounding a respective of said armature cores and around which said electrical coils are wound, circumferentially spaced, and radially extending interengaging parts carried by one of said radially inner and radially outer core elements engaged with a radially extending surface of the other of said radially inner and radially outer core elements for preventing axial shifting of said core elements in an axial direction relative to each other for maintaining the axial relationship between said core elements, said radially extending interengaging parts being formed at least in part by said bobbins.
