Rotor for a rotating electric machine, and rotating electric machine

A rotor for a rotary electric machine, which is able to interact with a stator of the rotary electric machine and rotates with respect to an axis of rotation, the rotor comprising:

• a body,
• permanent magnets,
• the body comprising a plurality of rotor teeth defining cavities in which the permanent magnets are accommodated,
• each rotor tooth comprising at least one holding part, the holding part comprising:
• a holding portion comprising a holding face (9) 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,
• wherein the radially outermost face has a first plane of symmetry parallel to the axis of rotation, and wherein
• the holding portion has a first end, with a first thickness, on a second plane parallel to the first plane and passing through an end part of the holding face, and wherein
• the wing extends circumferentially between the first end and a free second end, the second end being at a first distance from the radially outermost face of the permanent magnet,
• the first end being at a second distance from the first plane,
• the first end and the third end being at a third distance from one another,
• the ratio between the third distance and the second distance being between 0.09 and 0.45, in particular between 0.13 and 0.23, and the ratio between the first thickness and the first distance being between 0.04 and 0.86, in particular between 0.07 and 0.17.
