| Zusammenfassung: | A rotating device includes: a hub that is rotatably supported by a base, on which a recording disk is to be mounted; a stator core fixed to the base, the core having a ring portion and multiple salient poles that radially extend from the ring portion; and a magnet fixed to the hub, the magnet having multiple magnetic poles arranged along its circumference on its side surface on the salient pole side. The magnet is arranged such that its side surface on the salient pole side faces a side surface of each salient pole and a side surface of a portion of the hub that faces the stator core along a rotational axis direction. |
