CIRCULATING APPARATUS TO USE GAS BEARING

摘要

PURPOSE: A gas bearing circulator is provided to make at least some of a gas flowing into via a circulation housing unit pass through an internal space of a driving unit, thereby preventing a demagnetization phenomenon of a magnet arranged in the driving unit. CONSTITUTION: A gas bearing circulator comprises a circulation housing unit (110), a bearing unit (120), and a driving unit (140). The circulation housing unit includes: an inlet where a gas flows into; an outlet where the gas is discharged; and an internal space. The bearing unit includes: a first bearing which is mounted on an inlet region of the internal space of the circulation housing unit; and a second bearing which is mounted on an outlet region thereof. The driving unit includes: a stator which is mounted between the first and second bearings and which includes a coil; and a rotator which is mounted to be relatively rotated around the stator inside the stator and which one end is arranged in the first bearing and the other end is arranged in the second bearing. An impeller is mounted on the other end of the driving unit.
