筒型リニアモータ

Abstract

To provide a cylinder type liner morter capable of reducing a manufacturing cost.SOLUTION: A cylinder type liner morter 1 comprises: a core 7 made of a magnetic material that includes a cylinder yoke 7a and a plurality of projection poles 7b having an annular shape and provided in parallel along an axial direction to one of an inner periphery and an outer periphery of the yoke 7a; and a plurality of permanent magnets 6a and 6b that are mounted so as to alternately appear an N pole and an S pole in the axial direction to the core 7 in an annular shape. The cylinder type liner morter comprises: a core assembly 5 provided with a section with a magnet S1 in which permanent magnets 6a and 6b are installed, and sections S2 and S3 without magnet in which the projection poles 7b and 7b are provided and the permanent magnets 6a and 6b are not installed; and an armature 2 that is arranged on the projection pole 7b side of the inner periphery or the outer periphery of the core assembly 5 and can be relatively moved in the shaft direction to the core assembly 5, and has a plurality of windings 4 provided side by side in the axial direction of the core assembly 5 and opposite in a radial direction to the core assembly 5.SELECTED DRAWING: Figure 1
