INSULATOR, STATOR, AND MOTOR

Abstract: an insulator disposed between a stator core and a three-phase coil wound around the stator core includes a main body section that covers a portion around which the coil is wound in the stator core and insulates the stator core and the coil and a jumper wire holding section that is disposed on a radial direction outer side of the main body section and holds a jumper wire of the coil. the jumper wire holding section includes a first groove a in which a jumper wire at of an a-phase coil is housed, a second groove b that is disposed on an axial direction other side with respect to the first groove a and in which a jumper wire bt of a b-phase coil is housed, and a third groove c that is disposed on the axial direction other side with respect to the second groove b and in which a jumper wire ct of a c-phase coil is housed. the first groove a, the second groove b, and the third groove c are formed in different shapes.
