FIELD: electricity.
SUBSTANCE: invention is related to the field of electrical engineering, namely, to features of design versions of electric machines. In electric machine that contains stator and rotor, between poles of which working non-magnetic clearance is created, through which the main magnet flow passes, according to this invention, in abovementioned working non-magnetic clearance facility is installed to maintain this clearance as permanent made of non-magnetic wear-resistant material.
EFFECT: of reliability and durability of electric machine operation.
