Abstract: A rotor for a rotary electric machine that rotates with respect to an axis of rotation, includes a body and permanent magnets. The body includes a plurality of rotor teeth defining cavities in which the permanent magnets are accommodated, each rotor tooth including at least one holding part. The holding part includes a holding portion having a holding face against which a radially outermost face of the permanent magnet bears, a wing remote from the radially outermost face and in the circumferential continuation of the holding portion.

Abstract: A cooling system for a rotary electric machine having an axis of rotation includes a cooling jacket suitable for receiving a stator of the rotary electrical machine, a housing receiving the cooling jacket, in which an outer wall of the cooling jacket forms, with an inner wall of the housing, a cooling chamber through which a cooling fluid can flow. A separator element separates an inlet zone of the cooling chamber and an outlet zone of the cooling chamber. The separator element includes a fastening part, of a first length, fastened to the outer wall of the cooling jacket or the inner wall of the housing, a first separating part, of a second length, inclined relative to the fastening part and non-parallel to the fastening part. The first length is less than the second length such that the first separating part includes comprises a first free end that is not directly connected to the fastening part. The invention also relates to an electric machine equipped with such a cooling system.

Abstract: An assembly for a rotary electric machine includes a bracket having a recess for a rolling bearing, and a preloading member for preloading the rolling bearing, intended to be disposed axially between the end wall of the recess and the rolling bearing. Also included is a holding member for holding the rolling bearing, intended to be disposed radially between the rolling bearing and a lateral wall of the recess. The holding member for holding the rolling bearing is arranged so as to make it possible to axially hold the preloading member in the recess of the bracket before the rolling bearing is inserted into the recess, during a phase of assembly of the rotary electric machine.
