1. A stator comprising:
a stator core (11) including a base (111) of a circular shape, a teeth part (112) formed radially from the base (111), and a teeth end (113) extending to both sides in the circumferential direction at an end of the teeth part (112);
an upper insulator (12) coupled to an upper part of the stator core (11), including an upper base insulating part (121) for insulating an upper part of the base (111), an upper teeth insulating part (122) formed radially in the outer circumferential direction of the upper base insulating part (121), for insulating an upper part of the teeth part (121), and an upper teeth end insulating part (123) located over the teeth end (113), protruding upward at an end of the upper teeth insulating part (122);
a lower insulator (13) coupled to a lower part of the stator core (11), including a lower base insulating part (131) for insulating a lower part of the base (111), a lower teeth insulating part (132) formed radially in the outer circumferential direction of the lower base insulating part (131), for insulating a lower part of the teeth part (112), and a lower teeth end insulating part (133) located under the teeth end (113), protruding downward at an end of the lower teeth insulating part (132); and
a coil (14) wound around the teeth part (112),
wherein a coil hook (123A) on which the coil (14) is hooked is formed to protrude upward from an upper part of the upper teeth end insulating part (123), and
wherein a lower part of the coil (14) hooked on the coil hook (123A) is supported on a pair of coil support grooves (123B) formed at both sides of the lower part of the coil hook (123A).
