PROBLEM TO BE SOLVED: To provide a motor capable of facilitating assembly work for assembling magnets with a magnet holder that holds the magnets.SOLUTION: The motor comprises: a plurality of magnets which are arrayed in a circumferential direction radially inside of a rotor holder; and a non-magnetic magnet holder 22 for holding the magnets. The magnet holder 22 includes: a plurality of pillars 220 which extend axially and position the plurality of magnets in the circumferential direction; and a first ring 221 and a second ring 222 which mutually couple the plurality of pillars 220 at separated positions in the axial direction. The first ring 221 is positioned radially outside of the second ring 222 and the second ring 222 is positioned radially inside of outer peripheral surfaces of the pillars 220. Therefore, since a metal mold can be removed in a vertical direction after molding, the magnet holder can be integrally molded using a bidirectional metal mold.SELECTED DRAWING: Figure 2 |
