MOTOR STATOR Russian patent published in 2020 - IPC H02K1/14 H02K3/28 

FIELD: electrical engineering.

SUBSTANCE: invention is related to electric engineering, in particular to stators of AC motors. Stator of the electric motor includes a magnetic conductor in the form of a loop with teeth having a short-circuited turn, between which windings connected to an alternating current source are wound around the magnetic circuit of the magnetic circuit. Windings located on opposite sides relative to the tooth are connected in opposite directions to create differently directed magnetic flows. Magnetic conductor has even number of pairs of matched teeth. Each pair of teeth consists of a tooth directed inside the magnetic conductor circuit and a tooth directed outward of the magnetic circuit contour, with possibility of simultaneous arrangement of two rotors of electric motor: one rotor outside motor stator, and other rotor inside. Windings can be interconnected in counter-series or in counter-parallel.

EFFECT: increase of efficiency.
