Abstract
The magnetic wedge of embodiments is a magnetic wedge used for a rotating electrical machine and includes magnetic bodies having a planar structure having a principal plane. The principal planes of the magnetic bodies are disposed approximately perpendicularly to the air-gap surface between a stator and a rotor of a rotating electrical machine. The magnetic bodies have differences in the axial direction magnetic permeability in the axial direction of the rotating electrical machine, the rotational direction magnetic permeability in the direction of rotation, and the diametric direction magnetic permeability in the direction of the diameter.
