FIELD: electrical engineering. ^ SUBSTANCE: invention relates to electrical engineering, particularly to electrical machines and covers the rotor design. The novelty of this invention consists in that rotor (10) is furnished with cross piece (11) fitted to revolve around its axis and comprising several ribs (12) and active-steel laminated stack (14) made up of separate plates (16) concentrically enveloping the aforesaid cross piece (11) and jointed to it by cleaving wedges (13). The joint between stack (14) and cross piece (11) is provided for by making wedges (13) and stack plates (16) so that both enter each other with a geometrical match. Note here that, in compliance with this invention, the aforesaid stack plates (16, 16', 16") are furnished with several slots (18), with one side of every one said slot (18) is limited by dovetail-shape bearing side surface (17a, b) and with the other side being constricted by a side surface arranged at a slant angle. ^ EFFECT: simpler design, ease of manufacture, higher reliability and lower costs. ^ 5 cl, 6 dwg |
