Structure separable position sensor used in electromagnetic bearings

Magnetic bearings are widely applied in high speed and ultraclean situations for their advanced performance. The sensor is an important part of the whole magnetic bearing system, which influences the performance of the whole system directly. A novel transformer type sensor is designed in this paper, which is composed of two separate parts that automatically output differential signals. The FEM computation results and the prototype test results indicate that this kind of sensor has a good output performance, which possesses good application in this area.
