Abstract: A magnetic field generator includes a plurality of magnets on support members disposed opposite to each other across a gap. The plurality of magnets include: first magnets having a magnetization direction orthogonal to a support surface of each of the support members; and second magnets having a magnetization direction parallel to the support surface, and form a Halbach magnet array. Either of the first magnets or the second magnets has a first dimension orthogonal to the support surface which is smaller than a first dimension of the other of the first magnets or the second magnets, either of the first magnets or the second magnets being formed into a recessed shape as viewed from a side of the gap.

Abstract: A motor includes a stator that generates a rotating magnetic field; a rotor supported rotatably by a shaft within the stator; an outermost peripheral permanent magnet that is a permanent magnet embedded inside the rotor in an arced shape forming a convexity at the inner surface of the rotor; and an inner permanent magnet that is a permanent magnet embedded at the inside of the rotor in parallel to the outermost peripheral permanent magnet. The arc angle of the permanent magnets is greater than 90°, the thickness at the center of both inner permanent magnets is thinner than the thickness at the center of the outermost peripheral permanent magnet, and the thickness at the ends of both inner permanent magnets is thicker than the thickness at the ends of the outermost peripheral permanent magnet.
