Abstract
A stator for a rotary electrical machine, includes a stator core in a cylinder shape and having plural magnetic pole teeth, which are arranged in a circumferential direction of the stator while keeping a distance therebetween 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 provided between the coil and the corresponding magnetic pole tooth, and 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 being extended by a predetermined length, and an isolating member having a groove portion for accommodating and guiding the corresponding outgoing wire.
