较佳者,该线圈组件安装在支架20的侧壁,该支架20与承载台30对应地设置为呈矩形的框状结构,优选地,承载台30、支架20、线圈50和底座10呈同轴设置,承载台30、支架20、线圈50和底座10的中心轴均沿Z轴方向设置。该线圈组件包括两个线圈构件,线圈构件包括两个线圈50,两个线圈构件中的一者中的两个线圈50与沿X轴方向布置的两个磁性单体40一一对应,两个线圈构件中的另一者中的两线圈50与沿Y轴方向布置的两个磁性单体40一一对应。Preferably, the coil assembly is mounted on the side wall of the bracket 20, and the bracket 20 is arranged in a rectangular frame-like structure corresponding to the carrier 30. Preferably, the carrier 30, the bracket 20, the coil 50 and the base 10 are in the same shape.

Preferably, the four coils 50 are located at the same height, and The heights of the four coils 50 correspond to the heights of the four magnetic monomers 40 . Assuming that the axis position of the bracket 20 coincides with the axis position of the bearing table 30, then the X-axis positive direction, the X-axis negative direction, the Y-axis positive direction and the Y-axis negative direction of the bracket 20 correspond to a coil 50, and each coil 50 can generate magnetic induction with the magnetic unit 40 disposed on the corresponding side of the carrying platform 30 .
