SINE WINDING OF ELECTRIC GENERATOR Russian patent published in 1994 - IPC

FIELD: electric engineering. SUBSTANCE: sine winding according to integral manufacture technology has 2p coil groups, formed by N concentric turns of flat conductor, which are disposed onto isolating substrate. Number N is made according to the relation . Pitch of i-th turn is made to be equal to , when numbering from turn with largest pitch, where 1, 2 . . . N is number of turn of coil group at start of number from turn with largest pitch; τ is pole division width according to minimal diameter of location of active parts of conductors; Int is operator for separating entire part of number in brackets, achieved for N. The winding permits to reduce to 2-5 times winding factor. In this case, filtering properties, being determined by differential scattering coefficient, are 5-250 times larger depending on number N. Improvement in application of active materials is achieved due to increase winding coefficient for base harmonic more by 20% . EFFECT: efficiency. 2 dwg, 3 tbl
