Abstract:
An electric motor comprising:a rotor shaft; a rotor secured to the rotor shaft; a flange provided with a roller bearing for the rotor shaft; a stator having a cylindrical shell receiving at least one of a pair of ends of the flange, wherein the flange is fixed to the cylindrical shell by a fixing mechanism including a bayonet-type assembly that attaches the flange onto the shell through a relative displacement in an axial translation and a rotary relative motion; a commutator secured to the rotor shaft; a brush-carrying ring supporting a pair of brushes displaceable between a standby position separated from the commutator and a working position in contact with the commutator, said ring being housed in the shell proximate to one of said ends, wherein the flange includes a pair of axially projecting members that cooperate with said pair of brushes to displace the pair of brushes from the standby position to the working position when assembling the flange onto the shell.
