In a monography results of theoretical and experimental researches of non-salient pole DC machines with asymmetrical compensating windings on stator are brought. Features of the optimal designing of some DC machines types are considered. It is shown that Это и многое другое вы найдете в книге DC electrical machines: with non-salient pole stator and asymmetrical compensating winding (Vyacheslav D. Lushchyk)
