HIGH-RPM ASYNCHRONOUS ENGINE

FIELD: electrical engineering.SUBSTANCE: invention relates to electrical engineering, in particular to the designs of high-rpm asynchronous engines. Rotor of the high-speed induction motor is made massive, with grooves on the outer surface of the massive rotor, in which short-circuited winding in the form of rods is laid, which are galvanically connected at the ends of the rotor by rotating short-circuiting copper disks. In the central part of the rotor, a boring is made, in which a cylindrical hollow copper bushing is placed. Bore diameter D, as well as the outer diameter of the copper sleeve Dand its inner diameter Dare chosen from the following conditions: D≤D, where D- part of the magnetic circuit of the rotor outside of the magnetic flux, D=D, D
