TWIN AXIAL INDUCTION REGULATOR Russian patent published in 2001 - IPC

FIELD: voltage regulation. SUBSTANCE: device has two rotors mounted on common shaft. Parallel-connected three-phase primary windings are connected to line in forward and backward phase sequence. Series-connected secondary windings of two stators are connected to line in forward and backward sequence. Secondary windings of two stators are interconnected in series and also connected to line in forward and backward phase sequence. Stator and rotor magnetic cores are axial toroidal structures. Slots made in their end surfaces accommodate three-phase windings wound on respective magnetic cores. EFFECT: facilitated manufacture, reduced input of electric steel, improved make-up of regulator. 1 dwg
