Provided is a method for initially starting a motor. The method can improve the reliability to the start of the motor. In particular, even though the external load is at more than a predetermined level, a rotor located at an arbitrary angle can be aligned to an accurate initial position. Moreover, it can prevent the damage of the motor or the damage of the electronic device where the motor is installed. In order to initially align the rotor of the motor, a position on a stationary coordinate system, to which an alignment current of a rotation magnetic field is applied, is varied. |
