Abstract: A motor includes a stator, a rotor tube which is disposed inside the stator, a rotor core assembly which is coupled to an outer circumferential surface of the rotor tube, and a shaft which is coupled in the rotor tube. The rotor tube is divided into at least two stepped regions having different diameters. A multiple-row bearing has an inner wheel coupled to an outer circumferential surface of any one of the at least two stepped regions, and rotatably supports the rotor tube. Such a configuration ensures structural stability of the motor and minimizes a space occupied by a bearing.
