Patent ID: 8120227

Claim:
A rotor of a rotary electric machine, comprising: a rotor shaft mounted to rotate about its axis; a stack of laminations which is mounted coaxially on said rotor shaft and which comprises at least two radially projecting poles; a field coil which is wound around each pole so that axial end portions of said field coil, referred to as coil ends, project axially with respect to each outer axial end face of said stack of laminations; and at least two plates for supporting said stack of laminations, said at least two plates being made of a heat-conductive material and which are arranged axially on either side of said stack of laminations so that the inner radial faces of said at least two plates bear against said outer axial end faces, respectively, of said stack of laminations, housings provided in said inner radial face of each plate to receive said coil ends; wherein at least one of said housings has a contact surface with said outer axial end face of an associated coil end; wherein one of said plates has a filling orifice which opens into a bottom of a housing so as to allow injection of a liquid varnish around two ends of said field coil.
