    • PROBLEM TO BE SOLVED: To efficiently discharge heat of an armature coil.SOLUTION: In a surface plate 21, only for a cooling tube 71b among cooling tubes 71a and 71b respectively provided at a substrate stage side (+Z side) and the other side (-Z side) of an armature coil 38 configuring a planar motor, a fin-like projection part is provided on the inner wall of the cooling tube 71b to form the inner wall having a larger contact area with cooling medium compared with the cooling tube 71a. Thereby, a main heat transfer path for heat generated by the armature coil 38 is directed toward the cooling tube 71b side to discharge most of the heat generated by the armature coil 38 by cooling medium supplied to the cooling tube 71b. The remaining heat propagated to the surface plate 21 side is discharged by the cooling medium supplied to the cooling tube 71a, and thus, the heat generated by the armature coil 38 can be prevented from being transferred to an upper part of the surface plate 21. The armature coil 38 configuring the planar motor can be cooled, and fluctuation of an atmosphere around a substrate stage WST on the surface plate 21 can be suppressed.
    • 要解决的问题:有效地排出电枢线圈的热量。解决方案:在表面板21中,仅分别设置在基板台侧(+ Z侧)的冷却管71a和71b中的冷却管71b和另一侧 (-Z侧)构成平面电动机的电枢线圈38,与冷却管相比,在冷却管71b的内壁上形成有与冷却介质接触面积大的内壁的翅片状突起部 71A。 由此,由电枢线圈38产生的热量的主要传热路径朝向冷却管71b侧,通过供给冷却管71b的冷却介质排出由电枢线圈38产生的大部分热量。 传递到表面板21侧的剩余的热量通过供给到冷却管71a的冷却介质排出,从而可以防止由电枢线圈38产生的热量被传递到表面板21的上部。 能够冷却构成平面电动机的电枢线圈38,能够抑制表面板21上的基板台WST周围的气氛的波动。
