LINEAR MOTOR DRIVING TYPE FEEDING DEVICE |
摘要 |
A linear motor (20) is constituted of an armature coil incorporated in a movable slider (24) and a fixed magnet (22). The slider (24) and the driven body (14) of a laser beam machine united with the slider (24) are driven linearly. When the slider (24) and driven body (14) are driven, the magnetic attracting force acting between the slider and the magnet (22) is offset by the magnetic attracting force between another magnet (32) for compensation on the top of the driven body (14) and a stationary magnet (34) above the magnet (32). Therefore, the frictional resistances which act on linear guiding means (16a and 16b) during the movement of the driven body (14) are reduced.
