LOW-SPEED VALVE ENGINE OF INDUCTOR TYPE WITH BUILT-IN MAGNETIC GEARBOX Russian patent published in 2022 - IPC H02K49/06 

FIELD: electrical engineering.

SUBSTANCE: claimed engine contains three-phase low-pole winding on a stationary stator with a number of pole pairs p₁ from 1 to 3, direct current excitement winding on a bearing shield, a modulator with a number of ferromagnetic rods Z, a rotor with a charged core, on an outer surface of which Z₂=Z-p₁ open gears are located. At the same time, the rotor is made without permanent magnets. There are two implementations, in one of which the modulator is fixed, and an output shaft is connected to the rotating rotor, and in another one, the rotor is fixed, and the output shaft is connected to the rotating modulator.

EFFECT: provision of a structure of a low-speed valve engine of an inductor type with a built-in magnetic gearbox without permanent magnets, provision of a possibility of short-term forcing of an electromagnetic moment on a shaft of the claimed engine due to a short increase in current in coils exciting a magnetic field of a rotor.
