Study on Novel Measuring Method for Rotor Azial Displacement with Displacement Sensor fized on Radial Direction in Magnetic Bearing
In a magnetic bearing system, the rotor displacement measurement is an important foundation for rotors operating stably in high speed. In this paper, a novel displacement sensor structure based on LVDT (liner differential variable transformer) is proposed. The principle that axial displacement of magnetic bearing rotor is measured with displacement sensor fixed in radial direction is introduced. The characters of the displacement sensor proposed are analyzed in detail. The calculation and simulation results show that the displacement sensor proposed in the paper is feasible and the rotor axial displacement can be measured with the displacement sensor fixed in radial direction. This method can simplify the structure of magnetic bearings and reduce cost.
