前に比べ増加しないように構成したことを特徴と
するダンパ付ステツピングモータ。 In a stepping motor in which a rotor is formed by attaching a magnet and an iron core to a rotor shaft, the iron core is scooped out, a hollow container is attached to the hollow part, and a viscous fluid is placed in the container together with an inertial body. A stepping motor with a damper, characterized in that, by filling the damper, the rotor inertia after the damper is installed does not increase compared to before the damper is installed.
