Abstract
An N-phase electric machine includes a movable member mounted so as to move with respect to a fixed member, a system for determining at least one item of information relating to the movement of the movable member and an electric power supply system which is managed by the item of information, the determination system comprising an encoder having a magnetic track, the fixed member having an armature equipped with at least one conductive coil per phase, the coils being magnetically coupled to the track, the armature having pads around which a coil is respectively arranged, each of the pads having teeth spaced apart by hollows so as to direct the magnetic flux between the coil and the encoder so that the supply of electric power to the coils causes the encoder to move and/or the movement of the encoder causes electric power to be supplied to the coils.
