ULTRA HIGH-SPEED MICRO-GENERATOR Russian patent published in 2018 - IPC H02K21/22 H02K7/08 H02K5/167 H02K5/20 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used to provide power to autonomous objects. Rotor is made hollow. Stator is made of non-magnetic, non-electrically conductive material in the form of a ring with closed grooves and is located inside the annular permanent magnet of the hollow rotor, made in the form of an n-pole monolithic Halbach assembly and fitted with an interference inside the hollow rotor that is articulated to the turbine and compressor. Inner surface of the annular permanent magnet and the outer surface of the stator are coated with a hard material with a minimum coefficient of friction. Hollow rotor has a mechanical contact with the stator, forming a low-noise sliding bearing in the air gap. In the stator teeth, radial channels are provided with the possibility of supplying lubricant to the space between the stator and the hollow rotor.

EFFECT: technical result consists in reducing the physical visibility of objects equipped with these ultra-high-speed micro-generators, thanks to a reduction in noise, increase of the magnetic induction in their air gap and minimize their heat release.
