    • Especially for use in the semiconductor industry, a displacement device (701) is disclosed comprising a first part comprising a carrier (714) on which a system of magnets (710) is arranged according to a pattern of row and columns extending parallel to the X- direction and the Y-direction, respectively. The magnets in each row and column are arranged according to a Halbach array, i.e. the magnetic orientation of successive magnets in each row and each column rotates 90° counter-clockwise. The second part comprises an electric coil system (712) with two types of electric coils, one type having an angular offset of +45°, and the other type having an offset of -45° with respect to the X-direction. The first part (714, 710) is movable over a range of centimeters or more with respect to the stationary second part (712). For high precision positioning of the first part, an interferometer system (731, 730) is provided.

    • Positioning device with a first part and a second part which are movable relative to each other in at least one direction. Said first part comprises a carrier on which a system of magnets with N and Z magnets are arranged in an alternating manner and having a flux density B(x) = B(x + 2 tau ), tau being the magnetic pole pitch. Said second part comprises an electric coil system with at least one coil block unit, each unit having k coil blocks with k]2, said coil blocks having conductors, all conductors belonging to the same coil block being oriented in the same direction and fed by a n-phase system with n]2. Seen in a direction perpendicular to the conductors, the flux varies according to PHI = sin pi (x + xo)/2 tau . During the desired movement of the parts relative to each other, there is a small undesired up and down movement perpendicular to the desired movement. To avoid this undesired movement, the distance between the mass centers of the coil blocks belonging to a coil block unit, seen in a direction perpendicular to the conductors, is equal to tau /k +px tau , with p=2,3, .
    • 具有第一部分和第二部分的定位装置可以在至少一个方向上相对于彼此移动。 所述第一部分包括载体,具有N和Z磁体的磁体系统以交替的方式布置并且具有磁通密度B(x)= B(x +2τ),τ是磁极间距。 所述第二部分包括具有至少一个线圈块单元的电线圈系统,每个单元具有k个具有k] 2的k个线圈块,所述线圈块具有导体,属于相同线圈块的所有导体沿相同方向定向并被馈送 具有n] 2的n相系统。 从与导体垂直的方向看,磁通量根据PHI = sin(x + xo)/ 2 tau而变化。 在部件相对于彼此的期望运动期间,垂直于期望的运动存在小的不希望的上下运动。 为了避免这种不期望的移动,属于线圈块单元的线圈块的质量中心之间的距离在与导体垂直的方向上看到的等于τ/ k + px tau,p = 2,3。
