1. A stator comprising:
a stator core comprising a yoke and a plurality of teeth protruding from an inner surface of the yoke;
an insulator group surrounding a part of the stator core;
a coil wound around the insulator group; and
a molding portion disposed to cover the stator core, the insulator group, and the coil,
wherein the insulator group comprises at least one first insulator and a second insulator,
the at least one first insulator comprises:
a body portion around which the coil is wound;
an inner guide extending from an inside of the body portion in a direction perpendicular thereto;
a first outer guide extending from an outside of the body portion in a direction perpendicular thereto, having a planar inner lateral surface that is entirely inclined at a predetermined angle with respect to a top surface of the body portion;
a second outer guide disposed to be spaced apart from the first outer guide in an outward direction; and
a protrusion protruding inward from the second outer guide,
wherein an end portion of the protrusion is disposed such that a predetermined gap (G) is formed between the end portion and the first outer guide, and
wherein a part of the coil is disposed between the first outer guide and the second outer guide through the gap (G).
