1. Actuator assembly for a textile machine, having a width w, a depth d and a height h, wherein:
the actuator assembly comprises a plurality n of spools distributed along the depth d;
the actuator assembly comprises a plurality n+1 of magnetic plates distributed along the depth d;
the magnetic plates and the spools are alternated along the depth d such that each spool is received between two adjacent magnetic plates;
each magnetic plate comprises an upper permanent magnet and a lower permanent magnet having opposed orientation;
the upper permanent magnets of all the magnetic plates have the same orientation;
the lower permanent magnets of all the magnetic plates have the same orientation;
each spool is movable along the height h between an upper position and a lower position and vice versa, wherein the upper position is at least partially comprised between the upper permanent magnets of the two adjacent magnetic plates and the lower position is at least partially comprised between the lower permanent magnets of the two adjacent magnetic plates; and
each spool can be electrically powered in two opposed ways.
