Abstract

A fan motor is disclosed. The fan motor includes a heat dissipation fin (160). The heat dissipation fin (160) includes an outer ring part (161), an inner ring part (162) disposed inside the outer ring part (161), and a connection part (163) connecting the outer ring part (161) and the inner ring part (162). The inner ring part (161) 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 (160) can reduce a temperature of the bearing while enclosing the bearing (151), and improve concentricity (axial alignment) of the bearing (151).
