Abstract

Improved rotary electric machine and, in particular, alternator for the electric supply of motor vehicles, this machine comprising, on the one hand, a rotor consisting of two plates mounted perpendicularly on a rotor shaft, the two plates having parallel teeth on their periphery to the shaft and offset circumferentially and, on the other hand, a stator comprising a front side and a rear side, each bearing at least one bearing that supports the rotor shaft, the bearing being positioned longitudinally with the stator relation to the rotor shaft by axial tightening, characterized in that at least one ring spacer susceptible to elastic deformation is interposed in the stacking of rotor parts subjected to the aforementioned axial tightening, the spacer ring surrounding the rotor shaft, while the periphery of the spacer is supported, at least in a non-adjacent area between the rotor shaft, on one of the elements of said stack.
