摘要

"Permanent magnet clamping device inside a cylindrical breech of an electric motor inductor and electric motor starter motor". A permanent magnet clamping device within an electrically inductive cylindrical breech comprises elastic clamps (12) disposed between the permanent magnets to ensure angular positioning and axial and radial maintenance of said magnets against the inner wall of the magnet. breech. the end of each clamp (12) that first penetrates the breech during insertion of the permanent magnets, comprises means that facilitate axial sliding on the cylindrical inner wall of the breech, avoiding any contact with a terminal edge of said clamp, which is spaced apart. of the breech by at least one relief (17) provided over the web (16), and situated in retraction of the edge, and between the two axial locking fins (14) of the magnets.
