Abstract

A cooling structure of a linear motor (4) of the present invention comprises: magnetic field system portions constituted of two magnetic field yokes (5) made from a magnetic body oppositely arranged on a stationary base (1) with vertical intervals, and permanent magnets (6) having different magnetic poles alternating along the magnetic field yokes (5); armature portions constituted of armature cores (8) arranged parallel to the stationary base (1), between the magnetic field system portions with a gap in between, and armature coils (9) wound on the armature cores (8); an armature installation plate (7) provided above the armature portion and on which the armature portion is fixed; and a table (15) provided above the armature installation plate (7) and on which the work is mounted, wherein an intermediate plate (12) is provided between the armature installation plate (7) and the table (15), and a cooling path (17) is provided inside the intermediate plate (12) and the armature installation plate (7), so as to be continuously folded in the moving direction of the armature portions.
