Abstract
The present invention provides a shaft rotary type linear motor that enables a movable element to rotate and linearly move by using a simple structure, and can therefore support compact, space-saving and lightweight designs. The shaft rotary type linear motor includes: a shaft; an outer cylinder; a hollow movable element having a plurality of permanent magnets within the outer cylinder; an armature surrounding the hollow movable element and having a plurality of coils; and a frame containing the armature. The shaft is supported by a rotatable and linearly movable linear guide.
