Abstract
To simplify manufacture and improve concentricity of operation of the rotating parts of a claw pole generator with respect to the stationary parts thereof, in which the generator as such has no bearing elements and the rotating parts are supported solely from the shaft of the machine with which the generator is associated, the interfitting centering engagement of surfaces between the generator and the machine of the stationary part and also of the rotary part are all located at the side of the generator adjacent the machine, thereby avoiding accurate machining and positioning of generator elements with respect to other elements of the generator which, in turn, are located on the machine. In a preferred form, the field pole structure of the generator is fitted into the bore which receives the main bearing of the remote machine, thereby avoiding the necessity of forming another concentric positioning shoulder or the like on the machine end structure.
