Title:
DYNAMO-ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/090819
Kind Code:
A1
Abstract:
In this dynamo-electric machine (10) comprising a magnetic field element (20) having a magnet part (500), the magnet part has a magnet (501) in which a plurality of easy magnetization axes are oriented linearly and in parallel, and a plurality of magnet magnetic paths are formed along the easy magnetization axes. The magnet is divided at the d axis which is the magnetic pole center and the q axis which is the magnetic pole boundary, the magnet magnetic path is different from the magnet, a plurality of linear easy magnetization axes parallel to the d axis are oriented, and compared to a parallel orientation magnet (601) in which a plurality of magnet magnetic paths are formed along the easy magnetization axes, the magnet is configured so that a back electromotive force constant Ke is higher when the rotation angle of the rotor is within a first range including the center of gravity of the magnet.
