An apparatus for forming a leno selvage for a loom, comprising:

• a fixed-position housing;
• a bearing having an inner race and an outer race;
• a support having a shape of a circular ring or of a circular disk and rotatably supported in the housing by the bearing, the support having an outer periphery and two diagonally oppositely disposed thread eyelets for guiding leno threads adjacent the inner race of the bearing;
• at least two ring gears of magnetizable material extending in parallel with one another on the outer periphery of the support, wherein the at least two ring gears each have a radially outwardly directed toothed arrangement;
• a plurality of magnets arranged on the outer periphery of the support adjacent the at least two ring gears;
• a stator sheet package received by the housing and having a shape of a circular ring and segments, each segment carrying a coil and having a toothed arrangement on an inner periphery of the segment, the toothed arrangement of each segment corresponding to the toothed arrangement of the at least two ring gears adjacent the coils.
