The present invention provides a cylindrical linear motor that can develop great thrust and reduce thrust pulsations. The cylindrical linear motor includes a stator 1 and a movable element 10 disposed via a clearance with respect to the stator 1 and movable rectilinearly with respect to the stator 1. The stator 1 includes a stator core 3 having stator salient poles 3b, and a three-phase stator coil winding 2 inserted within the slots formed in the stator core 3. The movable element 10 has a plurality of permanent magnets 11 fixed to a movable element core 12. The cylindrical linear motor is constructed so that when the stator salient poles 3b are pitched at τs and the permanent magnets 11 are pitched at τp, a relationship of 3/4
