Abstract
The present invention relates to a cooling apparatus for an XY gantray, and more particularly to a cooling apparatus which cools an X-axis and Y-axis linear motors used when linear motors are employed for the XY gantry adapted to travel on the plane to perform works. The cooling apparatus for the XY gantry comprises: the X-axis and Y-axis linear motors having respective stator element and moving element, the stator element and moving element having through-holes formed in one side thereof so that external air is introduced therethrough to flow along surface of coil blocks included in the respective moving element of the X-axis and Y-axis linear motors, thereby cooling heat generated from the coil blocks. An advantage is provided in that heat generated from each of the coil blocks can be cooled by air flowing through the air passages provided by respective through-holes of the X- and Y-axis linear motors applied to the XY gantry.
