A rotor of a motor includes: a stator; a rotor core of a certain shape; a winding coil wound on the rotor core; and a rotor rotated by an electromagnetic interaction with the stator, in which both sides of an end wall of each slot of the I rotor core where the winding coil is inserted are respectively provided with a corner portion to connect both lateral walls of each slot. As a result, the effective area of a flux is increased thereby to decrease flux resistance and to reduce a stacked height of the rotor, that is, the number of stacked thin plates.
