Zusammenfassung: | PROBLEM TO BE SOLVED: To provide lithographic equipment, a device manufacturing method, and a positioning system. SOLUTION: The lithographic equipment comprises the positioning system having a first and a second electromagnetic actuators. Each actuator comprises two electromagnetic elements which mutually working together. These electromagnetic elements can move, with respect to each other by a force acting on the elements of each actuator. At least one side of the actuators comprises a shield for shielding one side of the actuators against a place generated by the other side of the actuators. This method can prevent a shielded actuator from being acted upon by a jamming force generated by the field. Further, a positioning system having actuators such as these is included.
