Abstract:
1. A rotating electrical machine comprising: a rotor core having an inner circumference portion and an outer circumference portion; a stator core opposed to the outer circumference portion of the rotor core; and permanent magnets radially extending inside the rotor core, the permanent magnets each having an incremental circumferential width in a direction from the inner circumference portion to the outer circumference portion of the rotor core, wherein the rotating electrical machine has a q axis, and wherein all of the permanent magnets are magnetized in magnetization directions across the q axis such that the magnetization directions are skewed relative to a direction orthogonal to the q axis, the magnetization directions of all of the permanent magnets being more than 0 degrees and less than or equal to 45 degrees relative to the direction orthogonal to the q axis.
