ABSTRACT:
An auxiliary power source comprising a generator driven by an electric motor or other drive means, the rotor of the generator has multiple core elements mounted side-by-side to provide a large number of poles and accordingly, a relatively high output frequency. Specially dimensioned pole faces eliminate cyclic air gap reluctance variations as an audible noise source.
