ELECTRIC MACHINE WITH ADDITIONAL MOVABLE SELF-DIRECTING STATOR Russian patent published in 2023 - IPC H02K16/04 H02K21/02 

FIELD: electrical engineering.

SUBSTANCE: invention is aimed to increase efficiency and reduce losses and heating of the electric machine due to the fact that the movable stator (6) does not rotate relative to the magnetic field of the stationary stator (1) and the magnetic field in it does not change, there is no continuous magnetization reversal, magnetic hysteresis is eliminated and no eddy currents are formed. A rotating DC commutator electric machine consists of a stationary stator (1) attached to the machine body (4), a rotor (2) mounted on a shaft (3) with the possibility of free rotation relative to the stator (1), since the machine uses magnetic induction for energy transmission between the stator and the rotor, and at least one additional movable stator (6), located coaxially inside the hollow rotor (2) and secured by means of bearings (5) to the inside of the rotor (2) or to the shaft (3) with the possibility free rotation both in relation to the stator (1) and in relation to the rotor (2). The rotor (2) is hollow and has windings (11). At least one movable stator (6) is made at least partially from ferromagnetic materials and is capable of self-orientation in accordance with the magnetic field lines created by the electric windings and/or permanent magnets of the stationary stator (1). The rotor (2) is located between the fixed stator (1) and at least one mentioned movable stator (6). The moving stator (6) concentrates and shapes the magnetic field B so that the magnetic lines are almost perpendicular to the rotor windings.

EFFECT: increased efficiency and reduced losses and heating of the electric machine.
