A magnet generator (1, 51, 61) comprising: a stator having a plurality of salient poles, each of which is configured of a magnetic path portion around which a coil is wound and a protrusion protruding laterally from a tip of the magnetic path portion; and a rotor arranged rotatably on an inner or outer circumference of the stator and having a plurality of permanent magnets attached in a circumferential direction to be opposite to the salient poles, characterized in that: the salient poles are configured such that every magnetic path portions has the same arrangement angle between the adjacent magnetic path portions; the salient poles have distal ends having surfaces that are arranged to be opposite to the permanent magnets, each surface of the distal ends includes an area of the magnetic path portion and an area of the protrusion; an arrangement angle between center positions of the surfaces of the distal ends in the circumferential direction that are in phase, is set to be the same as a pole arc angle of each of the permanent magnets; the salient poles adjacent only to the salient poles that are in phase have the protrusions disposed at both sides in the circumferential direction; and the salient poles adjacent to the salient poles that are out of phase have the protrusions disposed only at a side adjacent to each of the out-of-phase salient poles in either circumferential direction. a stator having a plurality of salient poles, each of which is configured of a magnetic path portion around which a coil is wound and a protrusion protruding laterally from a tip of the magnetic path portion; and a rotor arranged rotatably on an inner or outer circumference of the stator and having a plurality of permanent magnets attached in a circumferential direction to be opposite to the salient poles, characterized in that: the salient poles are configured such that every magnetic path portions has the same arrangement angle between the adjacent magnetic path portions; the salient poles have distal ends having surfaces that are arranged to be opposite to the permanent magnets, each surface of the distal ends includes an area of the magnetic path portion and an area of the protrusion; an arrangement angle between center positions of the surfaces of the distal ends in the circumferential direction that are in phase, is set to be the same as a pole arc angle of each of the permanent magnets; the salient poles adjacent only to the salient poles that are in phase have the protrusions disposed at both sides in the circumferential direction; and the salient poles adjacent to the salient poles that are out of phase have the protrusions disposed only at a side adjacent to each of the out-of-phase salient poles in either circumferential direction. the salient poles are configured such that every magnetic path portions has the same arrangement angle between the adjacent magnetic path portions; the salient poles have distal ends having surfaces that are arranged to be opposite to the permanent magnets, each surface of the distal ends includes an area of the magnetic path portion and an area of the protrusion; an arrangement angle between center positions of the surfaces of the distal ends in the circumferential direction that are in phase, is set to be the same as a pole arc angle of each of the permanent magnets; the salient poles adjacent only to the salient poles that are in phase have the protrusions disposed at both sides in the circumferential direction; and the salient poles adjacent to the salient poles that are out of phase have the protrusions disposed only at a side adjacent to each of the out-of-phase salient poles in either circumferential direction.
