Embodiment Construction
[0011] see figure 1 , which is a rectangular permanent magnet 1 placed on a suspended object 2 . Near the top of the suspended object, there is a rectangular electromagnetic coil 5, which is opposite to the rectangular permanent magnet 2, but the electromagnetic coil and the rectangular permanent magnet are dislocated by 90 in its initial state. , that is: the length direction of the electromagnetic coil is parallel to the width direction of the rectangular permanent magnet. A vertical position Hall sensor 4 is provided at the center of the lower part of the electromagnetic coil 5, and a circumferential position Hall sensor 3 is provided at the periphery of the lower part of the electromagnetic coil 5. 6 is an excitation current control circuit. 7 is the signal processing circuit of the position in the circumferential direction. 8 is the signal processing circuit of the position in the vertical direction.
[0012] see figure 2 , 4 is the vertical direction position Hall s...
