摘要
PURPOSE: A magnetic bearing device is provided to improve reliability of a displacement measurement of a rotational shaft floated by an electromagnet and to cool heat generated by a turbulence of the electromagnet. CONSTITUTION: A magnetic bearing device includes a rotational shaft(30). An electromagnet(20) is installed at an outer surface of the rotational shaft(30) in order to float the rotation shaft(30). A block(41) is installed adjacent to the electromagnet(20), and includes an inside surface separated from the outer surface of the rotational shaft(30). The block(41) includes at least two ejecting paths(42) for ejecting air to the outside surface of the rotation axis(30). A pressure sensing device is connected to a divergence path, and senses a position displacement of the rotational shaft(30) from the electromagnet(20) by sensing a pressure variation according to a variation between the inside surface of the block(41) and the rotational shaft(30).
