Electric motor comprising a rotor and a wound stator, the rotor comprising - a shaft and - two discs (22a, 22b) mounted fixed in rotation on the shaft and equipped with permanent magnets, an external portion (312a, 312b, 312'a, 312'b) of the stator extending axially at the level of each disc, parallel to an axis of rotation of the rotor and radially beyond this disc starting from the axis, the stator comprising - a plurality of separate bars (31, 31') which are produced in a magnetically conductive material and some parts of which form the external portion (312a, 312b, 312'a, 312'b) of the stator which extends axially at the level of each disc, parallel to an axis of rotation of the rotor and radially beyond this disc starting from the axis, and - a carrier structure holding the bars fixed relative to each other, the carrier structure being mounted with the possibility of rotation on the shaft axially outside the two discs (22a, 22b), the external portion (312a, 312b, 312'a, 312'b) of the stator extending, parallel to the axis of rotation of the rotor, axially outside the discs (22a, 22b) up to the level of the carrier structure, at least some of the metallic bars being bent and supporting windings, the windings being at least partially inserted into a cylindrical space (EC') disposed, along the axis, between the discs (22a, 22b) of the rotor, this cylindrical space (EC') having a diameter equal to the diameter of these discs, the length of the windings, measured parallel to the axis of rotation of the rotor, being independent of the length of the magnets, measured parallel to this axis, or the internal part (314', 316'a, 316'b, 35) of the stator comprising at least one winding wound around a bar made of magnetic material which likewise defines one part at least of the external portion (312'a, 312'b) of the stator, the bar supporting the winding being in particular bent (318'a, 318'b) in a direction where it displaces the winding towards the axis of rotation of the rotor, relative to the external portion (312'a, 312'b) of the stator, or each winding being centred on an axis parallel to the axis of rotation and offset radially relative to the latter, each winding being disposed in an angular sector relative to the axis of rotation, the maximum external diameter of the motor in the housing thereof being equal to or slightly greater than an ideal diameter, itself equal to the sum of the maximum diameter of the rotor, of twice the maximum thickness of an external part (312a, 312b, 312'a, 312'b) of a bar (31, 31') of the stator at the level of the discs (22a, 22b) and of twice an air gap disposed between the external part of the stator and the magnets of the rotor and the bars (31, 31') having at least one zone of lower radial thickness, at the level of their positioning part on the carrier structure and/or in alignment with the discs (22a, 22b) of the rotor. - a shaft and - two discs (22a, 22b) mounted fixed in rotation on the shaft and equipped with permanent magnets, - a plurality of separate bars (31, 31') which are produced in a magnetically conductive material and some parts of which form the external portion (312a, 312b, 312'a, 312'b) of the stator which extends axially at the level of each disc, parallel to an axis of rotation of the rotor and radially beyond this disc starting from the axis, and - a carrier structure holding the bars fixed relative to each other, the carrier structure being mounted with the possibility of rotation on the shaft axially outside the two discs (22a, 22b),
