Abstract: A rotor has rotor cores divided in the axial direction. A permanent magnet is mounted at the position of each of the magnetic poles of cores. The permanent magnet of each magnetic pole is configured by a single tabular member that penetrates the two divided cores in the axial direction. Convex parts are respectively provided on the outer peripheries of the respective magnetic poles of the rotor cores along the axial direction of the rotor. The convex parts are provided to positions that are displaced for each of the two divided cores. The magnetic flux density increases in the convex parts, which becomes the magnetic pole center. Since the convex parts positions are displaced to each other, a skew function can be exhibited even if the permanent magnet is mounted at the same position.

Abstract: An IPM type rotor having a continuous skew structure obtained by a simple means, without constituting a permanent magnet as a complicated shape and forming an inclined magnetizing pattern on the permanent magnet. A rotor core has a recess formed on an outer circumferential surface of the rotor core. The recess is formed so as to extend along a boundary line of magnetic poles of a desired skew structure. Therefore, even when each permanent magnet has the cuboid shape, the magnetic flux may be uniformed during the magnetic flux is transmitted through the magnetic steel plate having high permeability, whereby the magnetic flux within the gap having low permeability becomes dominant. As a result, the rotor having the continuous skew structure is obtained.
