Abstract:
A cylindrical linear motor includes a stator and a movable element disposed via a clearance with respect to the stator and movable rectilinearly with respect to the stator. The movable element has a plurality of permanent magnets fixed to a movable element core. The stator salient poles 3b are pitched at τs and the permanent magnets 11 are pitched at τp so that a relationship of 3/4
