Abstract
A fan motor includes a heat dissipation fin. The heat dissipation fin includes an outer ring part, an inner ring part disposed inside the outer ring part, and a connection part connecting the outer ring part and the inner ring part. The inner ring part is elastically deformed to be inclined in parallel to a rotational shaft which is inclined when axial alignment between bearings is not made. Accordingly, the heat dissipation fin can reduce a temperature of the bearing while enclosing the bearing, and improve concentricity (axial alignment) of the bearing.
