An inductor machine with an armature winding common for all the stator packs and a stationary annular field winding disposed under the armature winding intermediate the toothed rotor packs, differing from the prior art inductor machines in that the field winding is enclosed in a member made up of one or two flanges enveloping the field winding and attached to the end faces of keys equidistantly arranged along the circumference of the inner surface of the machine frame.
An inductor machine comprising, a frame, at least two stator packs attached to said frame and carrying a common armature winding, a toothed rotor having a number of packs corresponding to that of the stator packs, a field winding in the form of stationary annular coils disposed under said armature winding between said rotor packs, at least one mounting flange fixed to the frame and adjoining side faces of said annular coils, fastening means fixing the mounting flange to said frame and including individual prism-shaped keys arranged equidistantly on said frame at the inner surface thereof, said prism-shaped keys having axial holes for the fastening of said flange thereto, said flange being in the form of a disc having a central opening and an annular portion around the central opening receiving said field winding, said disc having a plurality of holes along the periphery thereof for receiving fastening means engaging said holes in said keys, said flange have grooves in the spaces between said holes in said disc for the axial flow of cooling air.
