The Shimpo RK‑3D is a compact electric pottery wheel with a direct‑drive motor, which reduces vibration, noise, and maintenance by eliminating belts. Speed is continuously adjustable and typically controlled via a foot pedal, enabling hands‑free operation while throwing. The wheel supports both clockwise and counter‑clockwise rotation, making it suitable for both right‑ and left‑handed users.

The wheel head has a diameter of about 300 mm and is made of aluminum. The machine can be used with bat plates. A removable splash pan helps contain water and clay and simplifies cleaning.
