Abstract: Multiple magnet units are provided in a rotor. Each of the magnet units includes multiple magnets. In the magnet unit, the multiple magnets are arranged in a circumferential direction. An outer surface of the magnet includes a first magnet surface. The magnet includes multiple magnet pieces stacked in a light direction. An outer surface of the magnet piece includes a first piece surface. The first magnet surface extends in a planar shape to span the multiple magnet pieces. The first magnet surface has multiple first piece surfaces. In the first magnet surface, the multiple first piece surfaces are flush with one another.
