ELECTRICAL MACHINE AND ACTUATION OF THIS ELECTRICAL MACHINE Russian patent published in 2015 - IPC H02K7/20 H02K3/28 H02P9/08 

FIELD: electricity.

SUBSTANCE: this invention is referred to an electrical machine, in particular, the electrical machine represents a synchronous generator designed so that it may be connected to a gas turbine or a hydroturbine. The electrical machine comprises the first rotor core with the first rotor winding, the first stator core with the first stator winding, an excitation device to feed current to the first rotor winding. The above excitation device includes the second rotor core with the second rotor winding. The second rotor winding is connected to the first rotor winding with rotation capability. The electrical machine contains also the second stator core with the second stator winding. The second rotor winding and the second stator winding are represented by polyphase windings. The first and second rotor windings are interconnected. The excitation device represents an asynchronous machine.

EFFECT: development of the electrical machine not using electrical slip rings and capable of excitation at start-up.
