ASYNCHRONOUS GENERATOR WITH OUTPUT VOLTAGE CONTROL Russian patent published in 2022 - IPC H02K17/42 H02K1/16 H02K5/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to stand-alone asynchronous generators intended for use in wind turbines operating in difficult conditions of an aggressive environment with the need to stabilize the output voltage. The asynchronous generator contains generating and regulating parts separated by a hermetic partition. The generating part contains a stator with a winding, in the bore of which a rotor with a squirrel-cage winding and permanent magnets is installed. The stator winding passes through a sealing input to the control part into an additional magnetic circuit - a toothed core, fixedly mounted coaxially with the rotor. An additional toothed core with a three-phase winding is concentrically mounted on the toothed core, the output ends of which are led out of the housing through a sealed input. A coaxially located cylindrical toothed core with conductors of a three-phase winding in the grooves is installed with the possibility of rotation around a common axis relative to the coaxial toothed core with the stator winding. A calibrated spring is installed between the toothed cores, which limits their movement.

EFFECT: stabilization of the output voltage when the generator load changes.
