Design Aspects of a Homopolar Inductor-Alternator

A design procedure for homopolar inductor-alternators is worked out. Special features such as field factors on an open circuit, reactances of armature reaction, computation of the short-circuit characteristic, and copper and iron losses are discussed. The stator leakage reactance, which forms an important parameter in the design and operation of these alternators is reviewed. The design of an eventual damper winding for these alternators is carried out, and the design details of a typical alternator are computed as an example.
