Abstract

Provided is a cylindrical linear motor having a structure for cooling both a mover (or an armature) side and a stator (or a field) side simultaneously without disposing any cooling pipe on the side of the mover (or the armature). Further provided are a cylindrical linear motor, which can be simplified in its cooling structure, which can be reduced in its size, weight and price and which can be simplified in an apparatus (or an industrial machine) for mounting the linear motor, and a method for manufacturing the stator of the cylindrical linear motor. The cylindrical linear motor comprises a mover having a plurality of coils in a housing, and a stator having hollow cylindrical magnets (2b) and pole pieces (2c) arranged alternately in a cylindrical member (2a) and having a coolant conduit (2d) on the radially inner sides of the hollow cylindrical magnets (2b). The pole pieces (2c) have coolant passages (2f), and the cylindrical member (2a) has cooling holes (2e) of the same number and at the same positions as those of the coolant passages (2f) of the pole pieces (2c).
