Abstract
An automotive alternator includes a rotor fixed to a shaft rotatably supported in a case, and a stator provided with a cylindrical stator core supported in the case so as to envelop the rotor, slots extending axially being formed in the stator core so as to line up in a circumferential direction at a ratio of two per phase per pole, and a stator winding constructed by installing a conductor wire coated with an electrical insulator in the stator core, a relationship between a radial dimension (d) of the conductor wire coated with the electrical insulator and a circumferential width dimension (L) of the slots being 2d<L.
Claims10
An automotive alternator comprising:
- a rotor fixed to a shaft rotatably supported in a case;
- and
- a stator provided with:
- a cylindrical stator core supported in said case so as to envelop said rotor, slots extending axially being formed in said stator core so as to line up in a circumferential direction at a ratio of two per phase per pole;
- and
- a stator winding constructed by installing a conductor wire coated with an electrical insulator in said stator core,
- a relationship between a radial dimension (d) of said conductor wire coated with said electrical insulator and a circumferential width dimension (L) of said slots being 2d<L,
- wherein a deformable plug is disposed inside an opening portion of said slots, and a cut portion is formed in said plug.
