ABSTRACT:
An electrical machine, especially an alternator, has a housing axially split into two generally symmetrical halves in which a rotor shaft is journaled. Held between the two housing halves are radial extensions of stator teeth which are bracketed by two relatively offset sets of rotor poles mounted on the shaft, the teeth being interconnected within the rotor by an annular magnetic yoke. A stationary excitation coil, surrounding a split inner hub of the rotor body, is carried by the yoke to generate a flux magnetizing the poles. The teeth have wings closely spaced from the orbital paths of the poles and also have webs, about half as wide as their wing span, enveloped by armature windings in which the output voltage of the alternator is induced upon a turning of the rotor.
