Abstract:
A second insulator mounted on a tooth is provided with: a second winding drum portion disposed on an end surface of the tooth; a conducting wire guide groove formed in the second winding drum portion to house a conducting wire so as to guide the conducting wire from the yoke side to the projecting end side of the tooth; a yoke-side conducting wire lead-in groove for leading the conducting wire into the conducting wire guide groove; a yoke-side conducting wire guide surface that makes contact with the conducting wire, being led into the yoke-side conducting wire lead-in groove, so as to prevent the conducting wire from floating; a tooth-side conducting wire lead-out groove for leading out the conducting wire from the conducting wire guide groove; a tooth-side conducting wire guide surface that makes contact with the conducting wire that has been led out from the tooth-side conducting wire lead-out groove, so as to prevent the conducting wire from floating; and a tooth-side conducting wire lead-in groove for leading the conducting wire, being prevented from floating by the tooth-side conducting wire guide surface, to the second winding drum portion side. A coil is formed by winding the conducting wire being led in from the tooth-side conducting wire lead-in groove around the tooth.
