FIELD: electrical engineering.
SUBSTANCE: rotor of high-speed electric machine comprises alternating-pole magnetic system including permanent magnets magnetized in tangential direction, and poles arranged between them. Invention feature is implementation of rotor poles in the form of a row of ferromagnetic sector plates electrically isolated from each other, coupled in axial direction to each other by means of two ring joints of “mortise and tenon” type, located on surfaces of sectors one above another in radial direction. A set of sector plates is fixed at the ends with flanges made of non-magnetic high-strength steel or titanium by means of similar joints of the “mortise and tenon” type, as well as by means of tightening pins.
EFFECT: increasing the reliability and durability of the electric machine.
