FIELD: electromechanical engineering; off-line power supplies built around induction generators with field capacitors. ^ SUBSTANCE: proposed composite stator winding has 18 coil groups. Finishing lead of coil group 1 is connected to starting lead of coil group 10; finishing lead of coil group 3, to starting lead of coil group 12; finishing lead of coil group 5, to starting lead of coil group 14; finishing lead of coil group 7, to starting lead of coil group 16; finishing lead of coil group 9, to starting lead of coil group 18; finishing lead of coil group 11, to starting lead of coil group 2; finishing lead of coil group 13, to starting lead of coil group 4; finishing lead of coil group 15, to starting lead of coil group 6; finishing lead of coil group 17, to starting lead of coil group 8. Star constituting leads are taken from starting leads of coil groups 3, 9, and 15. Additional delta-constituting leads are taken from integrated finishing leads of coil groups 4, 6, 8, from integrated finishing leads of coil groups 10, 12, 14, and from integrated finishing leads of coil groups 16, 18, 2; from integrated starting leads of coil groups 5, 7, from integrated starting leads of coil groups 11, 13, and from integrated starting leads of coil groups 17, 1. Field capacitors are connected to winding star or delta depending on desired voltage across generator output. In this way different voltages can be obtained across generator output at constant speed of drive motor. ^ EFFECT: enlarged functional capabilities of induction generator. ^ 1 cl, 8 dwg |
