This article describes generators with high-efficiency winding construction, applied to small-scale and large-scale wind turbines. Electromechanical converters, based on these compact winding generators, are promising for all types of stand-alone installations. Here a squirrel-cage induction generator with innovative stator is studied. Stator winding construction features reduced cross section of connection spots between rectangular slot and overhang parts of winding turns. This compact construction is expected to be beneficial for different types of electric motors and generators. A new design methodic of induction generators for wind turbines, provided by authors, considers construction features of compact windings. Resistance and end-winding leakage calculation peculiarities are described, and compact winding's influence on size and efficiency of generator is estimated. Research results of electromagnetic field, which are given in this article, should be considered in design of generator. Calculations have shown that compact winding construction results reduced the size and improved efficiency of the proposed induction generator. Reduced end-windings of generator allow placing power electronic units on the stator core inside the machine housing. Directions of further researches are pointed in the article, induction generators design technologies improvement in particular.
