ELECTRIC MACHINE Russian patent published in 2020 - IPC H02K1/14 H02K3/28 H02K16/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, particularly, to alternating current electric machines. Proposed machine comprises coaxially arranged rotor, inner and outer stators. Inner stator represents stator-inductor, comprising magnetic conductor in form of contour with even number of pairs of matched with each other directed inside tooth contour and outward directed contour bases of teeth and located on the magnetic conductor on opposite sides relative to each winding of the winding, connected to the alternating current source and configured to create differently directed magnetic flows. External stator represents stator-generator, on internal teeth of which there are windings connected to load. Number of internal teeth of stator-generator corresponds to number of bases of stator-inductor teeth, and they are located opposite each other through isolated gap.

EFFECT: increase of power conversion ratio.
