ABSTRACT:
The invention relates to a handling device including a track (1) constituting a travel path for one or more mobile elements, the said mobile elements being driven by a linear electric motor composed of an inductor (42, 43) carried by the mobile element and extending parallel to the track, and of an armature (4, 5) carried by the track and extending along the latter in such a way as to be able to cooperate with the inductor.
According to the invention, the said inductor (42, 43) and the said armature (4, 5) have, as viewed in cross section, the former, a rectangular shape defining three active faces and one inactive face, and the second, a U shape defining three active faces and suitable for housing the inductor in such a way that the respective active faces of the inductor and of the armature cooperate with one another, two by two.
