Stray Losses in Synchronous Electrical Machinery [PDF]
Nature, 1945 The earlier part of the paper discusses the problem of eddy currents from the point of view of the effect of the physical arrangement of an alternator on the stray losses. The later Sections deal with the components of stray loss, and, since these can be classified conveniently in accordance with their position in the alternator, the stray losses which
