An embodiment relates to a stator and motor, the stator comprising: a stator core having teeth; and a coil wound on the teeth, wherein each tooth comprises a body around which the coil is wound, and a shoe connected to the body, and the shoe comprises a plurality of grooves, and the width of the grooves, which are in the circumferential direction, is 90-110% of the width of a slot opening between the teeth. In addition, the motor forms grooves on the teeth of the stator, increasing the main cogging differential, thereby providing the benefit of significantly reducing the cogging torque.
