Abstract
A motor assembly includes a rolling bearing installed on a rotation shaft between an impeller and a rotor to support a first support of the rotation shaft, and a motor housing having a stator. The motor housing has a gas bearing bracket for accommodating a second support of the rotation shaft disposed at a side opposite to the first support with respect to the rotor. The motor assembly includes a gas bearing assembly in the gas bearing bracket to support rotation of the second support of the rotation shaft. The gas bearing assembly includes a gas bearing for surrounding the second support. The gas bearing is spaced apart from the second support of the rotation shaft to define a gap therebetween when the rotation shaft rotates. The gas bearing assembly includes an elastic member interposed between the gas bearing bracket and the gas bearing to elastically support the gas bearing.
