Abstract
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′″).

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
