The blower comprises a motor shaft system; the motor shaft system comprises a motor shaft, a second rotating shaft, and a third rotating shaft; a second air radial bearing, a thrust disk, a heat dissipation impeller, and a second locking nut are sequentially and fixedly sleeved on the second rotating shaft from inside to outside in the axial direction; a third air radial bearing, a blower impeller, and a third locking nut are sequentially and fixedly sleeved on the third rotating shaft from inside to outside in the axial direction; a sum of products of respective weights of the second rotating shaft, the thrust disk, the heat dissipation impeller, and the second locking nut and distances from centers of mass thereof to the central position of the motor shaft is equal to a sum of products of respective weights of the third rotating shaft, the blower impeller, and the third locking nut and distances from centers of mass thereof to the central position of the motor shaft. The blower ensures that the air radial bearings at the two sides are evenly stressed, such that the service life of the air radial bearings is improved.
