PURPOSE:To improve potential distribution and increase series static capacity by inserting the windings of flat square wire whose number of turnings is changed by the number of turnings of a unit coil to give a prescribed potential difference between the turnings of transposition winding wound continuously. CONSTITUTION:Disc winding is formed of winding segments I and III, and in the segment I, transposition winding A continuously wound and the inserted winding of flat square wire B which is wound between the turns of A and whose number of turns is changed by that of about two unit coils so as to give a prescribed potential difference are provided. That is, the winding A beings with the outermost turn A1 of the first unit coil a in the segment I and ends with the outermost turn A32 of the last unit coil d. The winding B begins with the outermost turn B1 of the third unit coil c and ends with the turn B32 of a unit coil b. While in the segment III, winding B whose number of turns is changed by that of about 1/2 coil compared with the turns of two unit coils of winding A which form a twin coil is wound between the turns of the winding A, and this combination is repeated hereafter. |
