SYNCHRONOUS-ASYNCHRONOUS ELECTRIC MOTOR Russian patent published in 2021 - IPC H02K17/26 H02K19/14 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used as high-torque motors in an electric drive. A synchronous-asynchronous three-phase electric motor contains several stator-rotor pairs inserted into each other. The magnetic cores (1) of the stator contain three-phase windings (5) connected in parallel to each other in a "star" phase and laid in its grooves (4). The magnetic cores (7) of the rotor contain short-circuited windings (14) and permanent magnets (11). In operation, due to several coaxially arranged and inserted into each other elements of the stator-rotor pairs, a better use of the internal space is provided, due to which a high specific power of the electric motor and a large synchronizing moment are achieved.

EFFECT: increasing reliability and expanding the scope of application, due to possibility without the use of additional electric current and voltage and frequency converters to work, if necessary, with less power due to the use of several stator windings.
