ABSTRACT:
An electric linear motor of the axial type comprising a fixed armature formed by an elongate rail of U-shaped cross section comprising magnetic and electrically conductive material, and a mobile, elongate inductor disposed between the arms of the U. The inductor comprises an elongate magnetic core of square cross section surrounded along its length by a plurality of successive, coaxial, electrically energizable coils without magnetic components interposed between the ends of adjacent coils. Between these ends are air gaps communicating with air passages extending through each coil for cooling air to be propelled therethrough.
