Abstract
A permanent field magnet is disposed between two armatures parallel to each other, and includes a first field magnet section facing a first armature of the two armatures, and a second field magnet section facing a second armature of the two armatures that is different from the first armature. The first field magnet section includes a first main magnet that generates a magnetic field for the first armature and a first auxiliary magnet that increases magnetic flux of a magnetic pole of the first main magnet. The second field magnet section includes a second main magnet that generates a magnetic field for the second armature and a second auxiliary magnet that increases magnetic flux of a magnetic pole of the second main magnet. The first main magnet and the second main magnet, or the first auxiliary magnet and the second auxiliary magnet, are permanent magnets magnetized in the same direction.
