Abstract
An embodiment relates to a motor comprising: a shaft; a rotor coupled to the shaft; and a stator disposed on the outside of the rotor, wherein the stator comprises a stator core, an insulator disposed on the stator core, and a coil wound around the insulator, and the stator core is formed by arranging a plurality of unit stator cores in the circumferential direction, and a welded portion is formed by welding regions where unit yokes of the unit stator cores meet each other on the upper side and the lower side of the stator core. Accordingly, cogging torque and torque ripple of the motor may be reduced.
