TWO-DIMENSIONAL ELECTRIC MACHINE-GENERATOR Russian patent published in 2025 - IPC H02K51/00 H02K47/28 H02K7/18 

FIELD: electrical engineering.

SUBSTANCE: two-dimensional electrical machine-generator comprises an anchor with a winding and a brush-and-collector device of a DC machine and a rotor having a possibility of free rotation relative to each other. AC generator winding is additionally laid in armature slots and its output is connected to AC network by means of slip rings and brushes. Rotor housing inner cylindrical bore accommodates main poles arranged radially relative to each other and made from permanent magnets. Armature winding is connected to DC source through slip rings located on outer side of rotor housing. Brushes of brush-and-collector device fixed by brush holders in inner bore of rotor housing are located perpendicular to main poles. One wind turbine transmits torque via overrunning clutch to anchor. Another wind turbine transmits torque via overrunning clutch to rotor. DC source connection polarity is coordinated so that torques created by wind turbines rotating opposite to each other and armature winding from main poles coincide in direction.

EFFECT: increase in quantity, uniformity of supply of electric energy of three-phase alternating voltage, improvement of reliability and stability of power system operation.
