Реферат: 786,716. Winding lay-outs for dynamoelectric machines. FERNSEH GES. May 18, 1956 [May 20, 1955], No. 15562/56. Addition to 771,872, [Group XXXVII]. Class 35. In a polyphase motor whose stator and rotor are supplied with different frequencies by means according to the parent Specification, and having a sinusoidal flux distribution, the combined resistance of the source having a low D.C. resistance and the winding connected to it is equal to or less than :- where (ni) 2 and (ni) 1 are the ampere-turns of the two windings, T is the moment of inertia of the rotor, r is its radius, l is its length and lg the width of the air-gap between stator and rotor.
