Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A rotating electrical machine, comprising: a rotor that includes a rotating shaft, which rotates around a predetermined axis, and rotates together with the rotating shaft; a stator core that is substantially in a shape of a hollow cylinder, is made of a plurality of steel plates, which are substantially in a shape of a circular disc and stacked in an axial direction, and is disposed so as to surround an outer circumference of the rotor; a stator frame th…
