Abstract: A rolling bearing device that can be mounted around a shaft of a rotary electric machine of axis X, and axially above a rotor assembly. The rolling bearing device includes a rolling bearing having an inner race and an outer race that are centred on the axis; a target holder which is fixed to the inner race and extends radially with respect to the axis beyond the outer race, and in a base extended by an axial lip, a target which is secured to the target holder and is able to cooperate with a detection means for tracking the rotation of the race about the axis. The base of the target holder includes at least one axially protruding tab designed to axially deform when the base bears against the rotor assembly once the rolling bearing has been mounted on the shaft.

Abstract: Rotating electric machine provided with an axis X. The machine comprises a front part and a rear part. The machine comprises a rotor of axis X comprising two axial end surfaces, each provided with fan blades. The axial surfaces located on the side of the front part and on the side of the rear part. A stator comprises a stator body having slots. The stator comprises a winding installed in the slots and forming a front winding head and a rear winding head. The rotor and the stator are placed in a casing. The front winding head completely masks the blades of the axial surface located on the front side of the machine, along a direction perpendicular to axis X.

Abstract: The invention relates to a rotor for a rotating electrical machine, comprising: a central shaft, an annular core coaxial to the shaft, a winding extending radially around the core, a first claw-pole and a second claw-pole arranged axially on each side of the core and the winding. Each claw-pole of the rotor comprises a plurality of triangular teeth having a base that is tangent to the pole wheel and comprising a first side, denoted a, and a second side, denoted b. The ratio of 1-a/b is between 0 and 0.5, or 0 and ?0.5. The tip of the teeth of one of the claw-poles is equidistant between the ends of the bases adjacent to the tip of the teeth of the other claw-pole.
