  • Patent number: 8159093
    Abstract: A motor apparatus includes a movable portion including a coil and a tooth-like salient pole and a platen opposed to the movable portion. The movable portion and the platen move relative to each other by using a magnetic field generated by supplying a current to the coil. The platen includes a base material having a surface on which convex portions and first concave portions are periodically arranged, a first thermally sprayed layer formed on the surface of the base material by thermal spraying such that second concave portions are formed inside the first concave portions, and a resin filled in the second concave portions.
