PURPOSE:To simplify working and assembling by engaging a bearing member made of a nonmagnetic metal thin plate with the inner periphery of a cylindrical stator, and slidably supporting the outer periphery of a movable element, thereby omitting special parts such as a guide shaft and a bearing. CONSTITUTION:A bearing member 2 bent substantially in a cylindrical shape from a nonmagnetic metal thin plate is engaged with the inner surface of a cylindrical stator 1, and a movable element 3 is slidably supported to the member 2. Thus, a guide shaft, a bearing and a bearing bushing are omitted as compared with a conventional linear pulse motor using a linear ball bearing, the size, the number of parts, working and assembling steps of the motor are reduced to largely decrease its cost. |
