PURPOSE: A rotation-resistance reduction assembly for a rotor of a motor is provided to minimize a frictional-resistance of a circulating fluid by providing an inclined slot opening of a stator around which a coil is wound. CONSTITUTION: In a rotation-resistance reduction assembly for a rotor of a motor, both sides(13b,13c) of one of teeth(13) defining an opening(p) of a slot(12) around which a coil(20) of a stator(100) is wound are formed to be inclined in a rotation direction. The inclined angles of the both sides(13b,13c) are different from each other The inclined angle of the side(13c) located proximal to the rotational direction is higher than the inclined angle of the side(13b) distal to the rotational direction.
