ASYNCHRONOUS THREE-PHASE ELECTRIC ENGINE Russian patent published in 2021 - IPC H02K17/16 H02K16/02 H02K16/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering. Asynchronous three-phase electric engine contains several coaxial stator-rotor pairs. Magnetic cores (1) of the stator contain three-phase windings (11) connected in parallel to each other in a “star”, laid in its grooves (5), magnetic cores (13) of the rotor contain short-circuited windings (18). In operation, due to the use of several elements of stator-rotor pairs coaxially arranged and inserted into each other, the best use of the internal space is ensured, due to which high specific power of the electric engine is achieved, and its reliability is increased. Due to the use of several stator windings, it is possible to work with less power, if necessary, without the use of additional electric current, voltage and frequency converters.

EFFECT: increased reliability, improved adjustment capability.
