Claim 8:
9. A stator comprising:
a plurality of split cores each having a yoke and a tooth, the split cores being connected such that the yokes form an annular shape; and
coils each wound around each tooth with two insulating sheets interposed between the coil and the tooth, wherein
the two insulating sheets include at least one of a first insulating sheet and a second insulating sheet,
the first insulating sheet is located between a side surface of the tooth and the coil wound around the tooth, and wraps the coil,
the second insulating sheet is located between another side surface of the tooth and the coil wound around the tooth, and does not cover a part of the coil, the part being on a side of an adjacent coil,
the first insulating sheet and the second insulating sheet are adjacently located in the coils adjacent to each other,
the stator further comprising:
a first insulator covering a first end surface directed in an axial direction of the stator in the tooth; and
a second insulator covering a second end surface directed in the axial direction of the stator in the tooth, wherein
the coil is wound around the tooth via the first insulator and the second insulator,
the first insulator covers a part of both of the side surfaces of the tooth,
the second insulator covers a part of both of the side surface of the tooth,
for one of the two insulating sheets, both of end portions in the axial direction are located between the first insulator and the second insulator, and the side surface of the tooth, and
for another one of the two insulating sheets, both of the end portions in the axial direction are located between the first insluator and the second insulator, and the side surface of the tooth.
