Abstract: The present invention may provide a motor including a shaft, a rotor coupled to the shaft, wherein the rotor includes a rotor core and a plurality of magnets coupled to the rotor core, and a stator disposed to correspond to the rotor, wherein the stator includes a stator core, an insulator coupled to the stator core, and a coil disposed on the insulator. In this case, based on an axial direction, the plurality of magnets are disposed at the same position in a circumferential direction, the stator core includes a yoke and a tooth protruding from the yoke, the tooth includes a first region and a second region formed by dividing an inner surface of the tooth facing the rotor in the axial direction, the first region corresponds to a partial region of the inner surface in which a first notch and a second notch are disposed to be spaced apart from each other in the circumferential direction, the second region corresponds to a partial region of the inner surface in which the first notch and the second notch are not present, and an axial length of the second region is in a range of 17% to 35% of an axial length of the stator core.
