Abstract: A magnet includes one or more polar regions each having an arc shape and arranged in a circumferential direction. A magnetic focus center of each polar region is different from a center of an inner diameter of the one or more polar regions. A value obtained by dividing (i) dm, a distance from a straight line connecting ends of a first magnetic center line of the one or more polar regions to a center of the first magnetic center line, by (ii) db, a distance from a straight line connecting ends of a second magnetic center line of the one or more polar regions to a center of the second magnetic center line, satisfies certain values based on a number of the polar regions. db is determined based on the one or more polar regions having a magnetic focus center that corresponds to the center of the inner diameter.

Abstract: A magnet orientation device includes an upper plate disposed on a magnet raw material, a lower plate disposed below the magnet raw material, and dies disposed on sides of the magnet raw material. The upper plate has a convex upward arc shape. The upper plate includes a first magnetic region and a first non-magnetic region that surround the first magnetic region and the lower plate includes a second magnetic region and a second non-magnetic region that surround the second magnetic region. A lower surface of the first magnetic region provides a plurality of grooves and an upper surface of the second magnetic region provides a plurality of protrusions. A horizontal length of the first magnetic region is greater than a horizontal length of the magnet raw material and a horizontal length of the second magnetic region is equal to or less than the horizontal length of the magnet raw material.

Abstract: A motor includes a stator and a rotor rotatably disposed at an inner side of the stator or an outer side of the stator. The rotor includes a rotor core block including a plurality of rotor core segments that are arranged along a circumferential direction of the rotor, where each of the rotor core segments includes a plurality of electrical steel sheets that are stacked on one another. The rotor further includes a plurality of permanent magnets disposed between the plurality of rotor core segments, where the plurality of rotor core segments and the plurality of permanent magnets are alternately arranged along the circumferential direction of the rotor. The plurality of electrical steel sheets include bridges that connect the plurality of rotor core segments to one another along the circumferential direction of the rotor.
