TWO-PACK INDUCTOR ELECTRIC MACHINE WITH COMBINED EXCITATION (VERSIONS) Russian patent published in 2019 - IPC H02K21/14 H02K55/04 H02K16/00 

FIELD: electricity.

SUBSTANCE: invention relates to electric power industry, namely, to contactless synchronous electric machines with combined excitation. Two-package inductor electric machine with combined excitation contains two packages, in each of which stators contain laminated cores, with three-phase armature windings placed on them, ferromagnetic shaft, on which there are two ferromagnetic steel rotor cores with projections, radially magnetized permanent magnets with the same polarity, located between ferromagnetic rotor projections, fixed annular winding of axial magnetic flux excitation installed on inner side of ferromagnetic bearing shield. Three-phase windings of armature of two packages are electrically independent, made concentrated in the form of ring or ridge-type coils. Stators are made with shift equal to 30 electric degrees. Ferromagnetic steel rotor cores are turned relative to each other by 90 electrical degrees. Armature windings and excitation winding are made of superconducting material.

EFFECT: increased mass and power indices of electric machine.
