摘要：A field element core includes field magnet through holes and coupling part.The field magnet through holes are circularly disposed in a peripheral direction around apredetermined direction and are adjacent to each other in the peripheral direction toform a set. The field magnet through holes forming the same pair both extend along a

given direction that is defined for each pair, when viewed from the predetermineddirection. The coupling part is provided between the field magnet through holes formingthe same set and has ends as lateral surfaces, respectively. The entire lateral surfaces ofthe coupling part are curved to form a concave shape. Specifically, viewed from thepredetermined direction, only at a given position between both ends of the lateralsurface, a tangent of the lateral surface extends along an extending direction of thecoupling part. The same holds true for the lateral surface.
