Abstract
A motor includes a stator and a rotor rotated due to the interaction between the rotor and the stator. Since overhangs are protruded only from the circumference of a rotor core of the rotor facing the stator in the axial direction, manufacturing costs for improving performance and core loss of the stator are minimized. Additionally, since the rotor core is manufactured by iron powder metallurgy, the rotor core is conveniently designed.
