Abstract
According to one embodiment, a rotating electrical machine has a vibrating-element. The vibrating-element has spring bars and circular members which cover spring bars while a part is connected to spring bars. The spring bars are connected to first stator core connection portions, which are formed so as to be spaced out in a circumferential direction from each other at two locations on a side surface of the stator core. The stator frame is connected by the second stator core connection portions, which are formed by two locations which are different from the first stator core connection portions, of the stator core. The second stator core connection portions contain a position adjacent to a node portion of a circular mode of vibration of the stator core, in which antinodes and nodes of vibration alternately appear in the circumferential direction as the vibrating-element is attached to the stator core.
