Abstract: A shaft linear motor includes an armature portion, a magnetic way and a sealing resin. The armature portion includes a frame, two ribs and a bobbin. The frame is formed with a receiving space therein. The two ribs are disposed on an inner wall of the frame. The ribs are respectively formed with a sectional surface. The bobbin is disposed in the receiving space and formed with an axially penetrated hole. The magnetic way is linearly and movably disposed in the axially penetrated hole. The sealing resin is fully filled in the receiving space for wrapping the inner wall of the frame and the sectional surfaces.
