MULTIFUNCTION STATOR WINDING OF INDUCTION GENERATOR Russian patent published in 2005 - IPC

FIELD: electrical engineering.

SUBSTANCE: proposed multifunction winding has twelve pairs of concentric single-layer internal coils and double-layer external ones in each pair; first phase includes pairs 1, 4, 7, 10; second phase has pairs 3, 6, 9, 12; third phase has pairs 5, 8, 11, 2; single- and double-layer coils of different phases are differentially connected in phase. First phase leads are formed by starting leads of single-layer coils of pairs 1, 3, 5. Second phase leads are formed by interconnected starting leads of double-layer coils and finishing leads of single-layer ones of pairs 2, 10, 12. Third leads are formed by finishing leads of double-layer coils of pairs 1, 3, 5 and connected to additional twelve-pole winding. Main winding uses star or star-star connection and its leads are connected to load and to field capacitors; low-voltage load is connected to third leads. Such arrangement of winding makes it possible to build off-line power supplies for different current frequencies and voltages around capacitor-excited induction generators at constant speed of drive motor.

EFFECT: enlarged functional capabilities.
