HYBRID AXIAL ELECTRIC MACHINE-GENERATOR Russian patent published in 2017 - IPC H02K51/00 

FIELD: electricity.

SUBSTANCE: in hybrid axial electric machine-generator comprising a brush-collecting device of a DC machine, a magnetic circuit with an alternating current generator winding located therein, an axial wound armature and a rotor, the stator housing is made in the form of a hollow cylinder, to the end faces of which bearing shields are rigidly fixed, the stator housing and the bearing shields are made of a material with large magnetic resistance. On the inner end surface of the bearing shield from the side of the wind turbine a magnetic circuit with an alternating current winding is installed, the active surface of which is located axially to the adjacent active end surface of the rotor, and on the inner end surface of the bearing shield, a wound armature is installed, the active surface of which is located axially to the adjacent active end surface of the rotor; at the same time, the rotor is located between the magnetic circuit with the generator alternating current winding and the armature with the possibility of rotation relative to them, and has axially disposed main poles made of permanent magnets fixed rigidly relative to the shaft by means of a material with a high magnetic resistance. The brush holders of the brush-collecting device of the machine are fixed rigidly on the rotor shaft, taking into account that their axis is located perpendicular to the axis of the main poles and shifted by the angle of the physical neutral in the rotation direction of the main poles, while the armature winding is connected to the DC source through the brush-collecting device, contact rings located on the shaft, brushes, and a device excluding the flow of the reverse-direction current to the direct current source; simultaneously with this, a free-wheel clutch is located on the shaft, that transmits the torque from the wind turbine to the rotor shaft. The polarity of the DC source connection is matched in such a way that the torques generated by the wind turbine and the main poles from the armature winding coincide in direction.

EFFECT: increasing the number and uniformity of the electricity supply of m-phase alternating current, increasing the reliability and stability of the power system operation.
