FAN MOTOR |
摘要 |
A fan motor includes: a rotor configured to be rotated so as to generate air movement; a stator configured to rotatably support the rotor via a fluid dynamic pressure bearing; and a driving mechanism configured to rotationally drive the rotor with respect to the stator. The rotor comprises a hub fixed to an impeller. The stator includes a bottom housing which supports a sleeve. The fan motor is configured to have a thickness of 3.2 mm or less along the rotational axis R of the rotor. |
