POWER GENERATION SYSTEM Russian patent published in 2013 - IPC H02K21/14 H02K1/27 

FIELD: electricity.

SUBSTANCE: voltage control is carried out in particular due to mechanical displacement of parts of a rotor magnetic system relative to each other, control of which is carried out, for instance, along a feedback circuit, besides, the generator shaft is equipped with inner and outer bushings, freely moving relative to the shaft, at the same time the specified bushings are rigidly connected with one or several keys, and a part of the rotor magnetic system is rigidly connected with the outer bushing, while the second part of the rotor magnetic system is rigidly fixed on the shaft. Mutual displacement of magnetic system parts is carried out due to radial-reciprocal movement of bushings by means of axial action of an electromagnet connected with an inner bushing via a support-radial bearing.

EFFECT: provision of output voltage control from zero to maximum, with self-locking by output voltage removal, when a control signal is not available.
