摘要： This prismatic linear electric motor comprises an inductor constituted by an elongated prismatic core surrounded by coils themselves separated by magnetic strips ensuring the conduction of the magnetic flux to a movable armature of U-shaped cross-section, which encloses the inductor. This inductor presents three active faces opposite the two flanges and the web respectively of the movable U-sectioned armature, and the fourth face of the inductor which is not used is in contact with an electrically conducting support which acts as screen against magnetic leakages. Each flat coil enclosed by two magnetic strips is spaced apart from the adjacent flat coils by annular gaps delimited by the magnetic strips and means are provided to cause cooling air to circulate in each gap between the flat coils.

摘要： 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.

摘要： A high-power linear electric motor comprises an inductor constituted by annular coils surrounding a magnetic core of square or rectangular section, and an armature having an omega section enveloping this inductor on three sides, so as to ensure the passage both of the magnetic flux and of the induced currents. The armature comprises, outside, a magnetic layer extending upon the whole conductive layer, that is to say as well upon the upturned U central part as upon the two side horizontal flanges of the armature.
