FIELD: electrical engineering. SUBSTANCE: rotor core stack is built up of stampings 5 with semi-closed slots 6; center line of opening 7 in each slot is displaced in respect to that of slot through a/n value, where a is width of slot opening, n is natural number within the range of ∞. Each next core abuts preceding one by opposite side. EFFECT: improved power characteristics of squirrel-cage induction motors. 3 dwg
