Abstract
A planar motor includes a flat base element arranged in a plane, and substantially cuboidal first magnets arranged on the base element whose magnetization is perpendicular to the plane and which are arranged at evenly spaced intervals and with alternating polarity in a first direction and in a second direction. The planar motor also includes substantially cuboidal second magnets whose magnetization is parallel to the plane and which are disposed with alternating polarity in the first direction and second direction between the first magnets, so that each first magnet is surrounded by four second magnets. The first magnets are disposed on protrusions of the base element.
