Abstract
The invention relates to an electric motor having a rotor and a coiled stator, the rotor including a shaft and two disks that are rotatably fixed to the shaft and provided with permanent magnets, an outer portion of the stator extending from each disk axially parallel to a rotational axis of the rotor and radially beyond same, from the axis. The stator includes a plurality of disjointed bars made of a magnetically conductive material, certain parts of which form the outer portion of the stator. The stator also has a carrier structure holding the bars such that they are fixed in relation to each other, the carrier structure being mounted in such a way that it can rotate on the shaft, axially outside the two disks. The outer portion of the stator extends parallel to the rotational axis, axially outside the disks of the rotor, up to the carrier structure.
