発明の名称 (英語) ELECTRICAL GENERATOR
発明の概要(英語) An electrical generator comprises a stator having a plurality of protrusions for stator poles arranged on the outer circumferential surface of the stator body, and a rotor which is so provided as to be rotatable around the stator and includes a plurality of protrusions for rotor poles. The plurality of protrusions for stator poles consists of first and second groups of protrusions for stator poles which are formed with lower height along the rotational direction or the reverse direction of the rotor and separated by a predetermined length in the axial direction, wherein the first and second groups of protrusions for stator poles are constituted in such a manner that the protrusions for stator poles are arranged at intervals in the circumferential direction. The rotor has first and second rings separated by a predetermined length in the axial direction, and first and second groups of protrusions for rotor poles where half of the plurality of protrusions for rotor poles is arranged circumferentially at intervals on the inner circumferential surface of the first and second rings, respectively. The first and second groups of protrusions for stator poles are arranged at the same phase, and the second group of protrusions for rotor poles is provided while shifted from the axis by such a mechanical angle as the electrical phase is shifted by 180 degrees from the first group of protrusions for rotor poles.
