<p>The present invention relates to a linear motor stage having a repulsive force compensating device, which has a simple and economic structure, and which can efficiently reduce a repulsive force transmitted to a magnet track. The linear motor stage having a repulsive force compensating device according to the present invention comprises: a shifter including an electromagnet; a magnet track which has N-polar and S-polar that are alternatively arranged, forms an electromagnetic force with the shifter to move the shifter straight, and is moved straight in an opposite direct to the moving direction of the shifter by the repulsive force generated when the shifter is moved; and a repulsive force compensating device to reduce the repulsive force transmitted to the magnet track, wherein the repulsive force compensating device includes a pair of conductive sheets which are made of conductive materials, and are arranged to be spaced apart from each other along the moving direction of the magnet track.</p> |
