ABSTRACT:
A motor is disclosed. In accordance with an embodiment of the present invention, the motor includes a stator and a rotor, which is supported by the stator such that the rotor rotates. Here, the rotor includes a rotational axis, which is supported by the stator such that the rotational axis rotates, a rotating body, which rotates together with the rotational axis, and a hub, which has a ring-shaped body and a protruding part. Here, the ring-shaped body is interposed between the rotational axis and the rotating body, and the protruding part extends an outer circumferential surface of the ring-shaped body coupled to the rotating body. Thus, the motor can improve the coupling strength between the rotational axis and the rotating body, securing the rotating rotor's stability.
