Document Type and Number:
Japanese Patent JP5696137
Kind Code:
B2
Abstract:
An electromagnetic steel sheet formed body to be used in a rotor core in which a forward rotational direction and a reverse rotational direction are assigned to a clockwise direction along a circumferential direction around an axial center when viewed from a visual line including the axial center, wherein a first hollow portion, a second hollow portion, and a rib partitioning the first hollow portion and the second hollow portion is formed at the electromagnetic steel sheet formed body such that permanent magnets constituting a plurality of poles are arranged substantially at regular intervals at predetermined pole pitch angles along the circumferential direction, and that the permanent magnet disposed at one pole is arranged in a segmented manner as the first permanent magnet and the second permanent magnet, when viewed from the visual line, and wherein the first hollow portion when viewed from the visual line is located closer to a side of the forward rotational direction than a centerline passing through a center angle of the pole pitch angle, and is arranged such that a longitudinal axis of the first hollow portion obliquely intersects in the clockwise direction with respect to a line perpendicular to the centerline.
