    • PROBLEM TO BE SOLVED: To make a position sensor apparatus compact and improve the sensitivity of a position sensor in thrust directions.
      SOLUTION: The position sensor apparatus is provided with stators and a rotor. The stators have four groups of teeth in each layered steel plate for every 90 degrees and are formed by displacing and superposing three layered steel plates made by winding a sensor coil on each of the teeth. The rotor is a ring-like layered steel plate arranged at a prescribed interval inside the stators and is opposed to first-layer and third-layer stators. Changes in the inductance of each sensor coil at positions intersecting with each other of a second-layer stator are detected on the basis of two electric potential differences generated in first and second bridge circuits constituted in such a way as to include each inductance to measure displacements in radial directions. Changes in the inductance of each sensor coil of the first-layer and third-layer stators are detected on the basis of an electric potential difference generated in a third bridge circuit constituted in such a way as to include each inductance to form a slip sensor and measure displacements in thrust directions.
