DISPLACEMENT SENSOR AND A MAGNETIC BEARING SYSTEM USING THE SAME |
摘要 |
In a displacement sensor and a magnetic bearing system using the same, the displacement sensor comprises: a first coil unit comprising at least one coil; a second coil unit comprising at least one coil which is differentially connected to one side of the coil(s) of the first coil unit; a sensor drive means for driving a first power source voltage and a second power source voltage having the same drive frequency; and a detection circuit for extracting displacement data from a differential signal generated by the first coil unit and the second coil unit. |
