Abstract
To reduce the axial length of the dynamo electric machine--remote rotating apparatus combination, in which the remote rotating apparatus, typically, is a gas turbine, the operating shaft of the remote apparatus is formed with a conical recess, and a claw-type rotor, rotating between a fixed field structure and a fixed armature structure is formed with a hub having a conical projection fitting into the conical recess and no other bearing. The shaft, thus, can be terminated flush with the remote apparatus housing structure, which can be formed with additional locating elements, such as a flange, accurately concentric with the center of the shaft for positioning of the dynamo electric machine against the remote apparatus in accurately aligned position.
