Planar motor for positioning a load along a plane

A planar motor, comprising:

• flat base means arranged in a plane;
• substantially cuboidal first magnet means arranged on the base means, magnetization of the first magnet means perpendicular to the plane, the first magnet means arranged at evenly spaced intervals and with alternating polarity in a first direction and in a second direction;
• substantially cuboidal second magnet means, magnetization of the second magnet means parallel to the plane, the second magnet means arranged with alternating polarity in the first direction and the second direction between the first magnet means, each first magnet means surrounded by four second magnet means;
• wherein the first magnet means are arranged on protrusion means of the base means;
• wherein the second magnet means are arranged in grooves formed by two adjacent protrusions means;
• and
• wherein a width of the groove corresponds to a width of the second magnet means over full depth of the groove so that the second magnet means are supported literally by the protrusions.
