ABSTRACT:
Alternators/generators of axially disposed air gap conformity in which a unique combination of rotors and stators results in machines of high efficiency, simplified modular assembly and extension. Such machines can, moreover, be readily constructed to produce from a single alternator unit multiple voltages and frequencies and from a single generator unit direct current in multiple voltages.
