  • Electrical machine with damper to resist vibratory stresses mechanically, and corresponding damper
    Patent number: 10020708
    Abstract: An electrical rotating machine includes a stator (11) provided with teeth (14) around which a group of coils (19) is wound, an annular interconnector (22) resting on a stator lamination stack (11) provided with tongues (36) to which ends (191, 192) of the coils (19) are welded for the formation of phases (U, V, W) of the electrical machine, and a closure flange (74) for closing a housing (70) for receiving the stator (11). The machine also includes at least one damper (83) consisting of a deformable material, configured to be mounted so as to be compressed between the interconnector (22) and the closure flange (74) of the machine. The invention also relates to the corresponding damper.
