MOTOR-GENERATOR Russian patent published in 2021 - IPC H02K21/24 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to the design of synchronous motors and generators with a permanent magnet rotor. The effect is achieved by the fact that an even number of permanent magnets of the rotor with two pole pieces on each magnet are magnetized along the radius. The number of U-shaped cores of one stator shield installed on each end shield is half the number of permanent magnets. Concentric coils are installed in the grooves of the U-shaped stator cores, one concentric coil is the phase of the electric machine, the other concentric coil is the phase of the electric machine, shifted by 90 electrical degrees relative to the first phase. The geometric shift α between the U-shaped cores of the shields depends on the number of pairs of rotor poles.

EFFECT: invention increases the reliability and efficiency of the device.
