ELECTRIC MACHINE Russian patent published in 2010 - IPC H02K5/16 H02K19/00 H02K21/00 

FIELD: electric engineering.

SUBSTANCE: in proposed electric machine, comprising body arranged with the possibility to supply cooling gas into its cavity, equipped with end shields and facilities for supply of cooling gas to units arranged in body cavity, stator core equipped with winding, in cylindrical cavity of which there is a rotor installed with gap, comprising inductor and bearing unit, according to invention, bearing unit is arranged with the possibility of gas dynamic and gas static support of rotor, for this purpose outer surface of rotor is shaped as a cylinder, besides it is located in cylindrical cavity of bush fixed against slipping in end shields, between outer surface of bush and stator core cavity surface inverted to it there are longitudinal channels arranged, bush is installed with gap versus surface of rotor and is arranged of insulation non-magnet antifriction material, besides cavities of longitudinal channels are communicated with gap between bush and surface of rotor, at least via one circular row of through holes in bush wall.

EFFECT: high reliability of electric machine operation at high speed of rotor rotation without increase of its dimensions and weight.
