DISPLACEMENT SENSOR AND MAGNETIC BEARING SYSTEM USING THE SAME |
摘要 |
<p>In a displacement sensor and a magnetic bearing system using the same, the displacement sensor includes: a first coil unit including at least one first coil; a second coil unit including at least one second coil differentially connected to one side of the at least one first coil of the first coil unit; a sensor drive means for supplying a first power source voltage and a second power source voltage having the same drive frequency to the first coil unit and the second coil unit, respectively; and a detection circuit for extracting displacement information from a differential signal produced by the first coil unit and the second coil unit due to a change in inductances of the at least one first coil and the at least one second coil according to a position change of a displacement measurement object.</p> |
