SELF-EXCITED BRUSHLESS DC TURBINE GENERATOR Russian patent published in 2011 - IPC H02K31/00 H02K21/20 H02K57/00 

FIELD: electricity.

SUBSTANCE: there proposed is self-excited brushless DC turbine generator the feature of which is the possibility of self-excitation on magnetic and electromagnetic basis, as well as development of multi-turn series-parallel toroidal slotless winding of armature. At that, electric receivers without rotating parts will successfully operate also on DC, and electric AC receivers with rotating parts will be powered through inverter electronic devices. The proposed electric machine can be used as turbine generator at its being arranged in water flow medium, as well as wind-driven generator at its being arranged in air flow medium. As far as invented acyclic brushless DC machines are manufactured in big quantity, generation procedure of electric energy will change because obtained alternating current with further conversion to direct current with valve devices is expensive more than by two times than obtained DC with its further conversion to AC with inverter devices. As far as acyclic motors are manufactured (invented generators have reversibility), need for alternating current is no more actual. Future belongs to direct current. Mr. M. O. Dolivo-Dobrovolskiy, inventor of three-phase AC system, our compatriot (1861-1919) expressed his opinion on the above.

EFFECT: simple device and its high technical reliability which includes the need for constant surveillance.
