Abstract
A motor including a rotor and a stator that supports and rotates the rotor is disclosed. In accordance with an embodiment of the present invention, the motor includes a magnetic member, which is installed in the rotor such that the magnetic member faces the stator, and a stator magnetic body, which is a part of the stator and has a part corresponding to the magnetic member formed asymmetrically therein. In this way, the motor can prevent a whirling effect by installing the magnetic member, which forms a preload, even the motor is thinner.
