Abstract

See full text

The present invention relates to a rotor (1) of a rotary electric machine, comprising:

    a body (3) comprising a cylindrical central core (5) and a circumferential plurality of arms (B1 . . . B18) extending radially out from the cylindrical central core (5), the body (3) being intended to be mounted with the ability to move about an axis of rotation X,a coilset produced by windings of turns and forming at least one series of coils (C1 . . . C9, C1′ . . . C9′, C1″ . . . C9″, C1′″ . . . C9′″), a coil (C1 . . . C9, C1′ . . . C9′, C1″ . . . C9″, C1′″ . . . C9′″) comprising a predetermined number of turns around at least two arms (B1 . . . B18) of the body, two adjacent coils (C1 . . . C9, C1′ . . . C9′, C1″ . . . C9″, C1′″ . . . C9′″) of a series being angularly offset from one another with a partial overlap,in which the rotor (1) comprises at least one additional retaining loop (S1, S1′, S2, S2′) wound around at least two arms (B1 . . . B18) of which at least one is common to the arms (B1 . . . B18) around which is wound the last coil (C9, C9′, C9″, C9″), situated radially outermost, of at least one series and of which at least one is distinct from the arms around which the said last coil (C9, C9′, C9″, C9′″) is wound, so that the at least one additional retaining loop (S1, S1′, S2, S2′) partially overlaps the turns of the said last coil (C9, C9′, C9″, C9′″).
