2項記載のシリンダ位置検出装置。[Claims for Utility Model Registration] A stator assembly including a stator in which a plurality of magnetic resins formed by winding an 11th coil and a secondary coil are arranged at predetermined intervals in the circumferential direction, the central space of the stator is a cylinder. The rod is arranged so as to be almost concentric with the rod, and the rod is slidably penetrated through the center space, and is fixed at a predetermined location of the cylinder, and when the rod is made of a magnetic material, a small amount of the surrounding area is In both cases, a plurality of protrusions are arranged at a predetermined pitch in the axial direction on the surface facing the stator magnetic poles, and between the stator magnetic poles, there is a misalignment in the correspondence between the protruding portions of the rods and the magnetic pole tips. and the primary coils of each of the stator magnetic poles are individually excited by reference AC signals whose phases are shifted from each other according to the arrangement angle of the stator poles, whereby the reference AC signal is phase-shifted according to the linear position of the rod. A cylinder position detection device characterized in that: is obtained on the side of the secondary coil. 2. The cylinder position detection device according to claim 1, wherein the rod is provided with rotating protrusions at a predetermined pitch around the rod as the projections. 3. The cylinder position detection device according to claim 1 or 2, wherein a sleeve made of a non-magnetic material is fitted around the rod.
