TURBOGENERATOR UNIT OF THREE-PHASE CURRENTS OF TWO DIFFERENT FREQUENCIES Russian patent published in 2017 - IPC H02K19/26 H02K1/26 H02K19/36 

FIELD: electricity.

SUBSTANCE: proposed turbo generator contains a ferromagnetic stranded stator comprising two distributed three-phase windings of a three-phase alternating current of increased frequency F1 And power frequency FS=50 Hz with the number of pairs of poles p₁ and p₂. And p₁>p_2, and a rotating ferromagnetic rotor. The rotor consists of two parts, on the external surfaces of which there are two distributed excitation windings in the slots. DC excitation winding with pole pairs number p₁ is connected to the output of the brushless excitation device. Three-phase winding of excitation of an alternating current with the number of pairs of poles p₂ is connected through contact rings and brushes to a three-phase output of a reversible frequency converter.

EFFECT: reduction of the estimated total power of the converting devices, their total mass and dimensions.
