Patent ID: 8541912

Claim:
A planar motor, comprising: a flat base element arranged in a plane; substantially cuboidal first magnets arranged on the base element , magnetization of the first magnets perpendicular to the plane, the first magnets arranged at evenly spaced intervals and with alternating polarity in a first direction and in a second direction; substantially cuboidal second magnets, magnetization of the second magnets parallel to the plane, the second magnets arranged with alternating polarity in the first direction and the second direction between the first magnets, each first magnet surrounded by four second magnets; wherein the first magnets are arranged on protrusions of the base element; wherein the second magnets are arranged in grooves formed by two adjacent protrusions; and wherein a width of the groove corresponds to a width of the second magnets over a full depth of the groove so that the second magnets are supported laterally by the potrusions.
