Abstract:
1. A stator for a rotary electrical machine, comprising: a stator core formed in a cylinder shape and having a plurality of magnetic pole teeth, which are arranged in a circumferential direction of the stator while keeping a distance between the neighboring magnetic pole teeth and each of which protrudes in a radial direction of the stator core; a coil configured with a conductive wire wound around each of the magnetic pole teeth; an insulating bobbin formed in a cylinder shape and provided between the coil and the corresponding magnetic pole tooth, the insulating bobbin including circumferentially offset first and second axially extending portions, the first axially extending portion possessing a curved end surface, and the second axially extending portion possessing an end surface inclined relative to the radial direction of the stator core; an electric power supply portion arranged axially outwardly of the stator core, electrically connecting the coil with an outside of the stator, and including an outgoing wire, which corresponds to a portion of at least one of a winding start and a winding end of the conductive wire wound around the coil being preliminarily extended by a predetermined length, and an isolating member, at which a groove portion for accommodating and guiding the corresponding outgoing wire is formed; and a portion of the outgoing wire being positioned between the first and second axially extending portions of the insulating bobbin so that the portion of the outgoing wire is bordered on opposite sides by the curved end surface of the first axially extending portion of the insulating bobbin and the inclined end surface of the second axially extending portion of the insulating bobbin.
