Field winding

Abstract

The invention concerns an inductor comprising a plurality of so-called first conductors ( 100 to 109 ) substantially parallel to one another, at least three of said first conductors being substantially mutually equidistant and distributed over a surface ( 120 ), and an electric power supply ( 140 ) of said conductors adapted to circulate an electric current in the same direction in said conductors. Preferably, said conductors are more densely distributed at the ends of the surface ( 120 ) comprising them. Preferably, the inductor further comprises a plurality of second substantially parallel conductors perpendicular to the first conductors, the electric power supply circulating an electric current in the same direction on said second conductors. Preferably, the inductor further comprises a plurality of third conductors forming closed turns, the electric power supply circulating an electric current in the same direction in said third conductors. Preferably, the electric power supply successively powers the first, second and third conductors.
