Abstract
According to one embodiment, there is provided a rotating electrical machine including a core, a coil extending from the core, and an electromagnetic shield which is provided outside the core, and has a plurality of shoulders projecting toward the coil. The coil includes an insulator covering outside of a conductor, a resistance layer formed on a surface of the insulator and contacting the core, and at least one potential grading layer formed on a surface of the insulator adjacent to the resistance layer. A boundary between the resistance layer and potential grading layer is provided at a position farther from the core than a point on a surface of the coil, where a distance between the coil and a shoulder of the electromagnetic shield closest to the core is the shortest.
