Abstract:
The cylindrical linear motor includes: a stator 1 that has a plurality of coils 5 coiled in a cylindrical shape and arranged in an axial direction on an inner side of a metal pipe 4; a mover 2 disposed to face an inner side of the stator 1 with a magnetic gap therebetween and having a plurality of permanent magnets 6 inserted in the axial direction into a cylindrical can 9; shafts 8 inserted into the mover 2; shaft support members 7 for supporting the shafts 8 at both axial ends of the metal pipe 4; and shaft receiving member 10 each disposed at both ends of an inner side of the can 9 to be adjacent to the permanent magnets 6 and having a concave portion 10a for fitting to a cone of the shaft 8.
