ABSTRACT:
A moving-magnet type linear motor is provided with cooling blocks which are attached to each of stator bases alongside a coreless coil and which allow coolant to flow therethrough for cooling the coreless coil. Each of the cooling blocks has in a base end portion thereof a fluid passage for flowing coolant and at an extreme end portion thereof a plurality of sheet-like protrusions like fins which are arranged alongside a part of the circumferential surface of the coreless coil with a clearance between each protrusion and the next thereto. Each cooling block is thermally closely jointed with the coreless coil at the extreme ends of the sheet-like protrusions.
