ROTOR OF ELECTRIC MACHINE Russian patent published in 2013 - IPC H02K3/51 

FIELD: electricity.

SUBSTANCE: rotor (10) of an electric machine comprises a yoke (12) with axial slots (13) distributed along external periphery, into which rods (14, 15) of the rotor winding are laid, and their ends (16, 17) protruding axially from the yoke (12) form a front part (11), which by means of a retention device (19, …, 28) comprising a large number of radial bolts is retained from acting centrifugal forces, besides, according to this invention, the specified radial bolts (24) have heads (25) strongly connected with a rod (31), and several radial bolts (24) arranged one after another in axial direction press one common retention plank (23) stretching in axial direction outside to the front part (11) of the winding.

EFFECT: increased reliability of a rotor by provision of reliable fixation of radial bolts entering a retention device design.
