PCT No. PCT/FR88/00635 Sec. 371 Date Aug. 23, 1989 Sec. 102(e) Date Aug. 23, 1989 PCT Filed Dec. 22, 1988 PCT Pub. No. WO89/06063 PCT Pub. Date Jun. 29, 1989.An electric motor comprises a stator element made of magnetic material, a moving element made of magnetic material and carrying at least one permanent magnet and adapted to run along sections of the stator element while defining two constant air-gaps by means of which the magnetic flux of the permanent magnet closes up in said stator element, and at least one coil wound around at least one of said sections. At least a pair of stops delimits a given clearance for the moving element along the coil. The movable element bears against either of the stops as a function of the direction of the direct current applied to the coil and remains magnetically locked thereto by means of a magnetic portion of the stops through which passes part of the magnet flux.
