<p>Disclosed is an electrical steel sheet formed body that is used in a rotating element core which is given a forward rotation direction and a reverse rotation direction to the clockwise direction along the circumference direction around the axial center when viewed in a sight line that includes the axial center. First hollow parts, second hollow parts, and ribs partitioning the first hollow parts and second hollow parts are formed in the electrical steel sheet formed body, such that permanent magnets configuring a plurality of poles are positioned approximately equidistant at a prescribed pole pitch angle along the circumference direction when viewed in the sight line, and that a permanent magnet positioned at a given pole is positioned in a segmented manner as a first permanent magnet and a second permanent magnet. When viewed from the sight line, the first hollow part is located further on the normal rotation direction side than the center line that traverses the center angle of the pole pitch angle, and such that the longitudinal axis of the first hollow part obliquely intersects a perpendicular of the center line in the clockwise direction.</p> |
