Abstract:
PROBLEM TO BE SOLVED: To provide a coil for preventing the occurrence of a peak with a high electric-field strength.SOLUTION: A positioning device includes a planar motor having two sets of stators and translators. One set of the stator and the translator has a periodical magnetic structure, and another set of the stator and translator includes at least one coil applied to carry a current. The coil includes the wound strip of a sheeted conductive material, and the edge of the coil has a round profile.
Abstract:
PROBLEM TO BE SOLVED: To provide an actuator that improves heat dissipation of a coil and acquires a large output. SOLUTION: An actuator includes a coil 3, a cooling body 5 configured to cool the coil 3, a quantity of heat transfer materials 8 fixedly arranged between the cooling body 5 and the coil 3, and a mechanical attacher 10 configured to attach the coil 3 to the cooling body 5.
