<p>The device has movable bodies arranged rotationally symmetrical to a fixed track. A stationary raceway comprises a precisely low point. An energy feeding device supplies necessary energy to each movable body. Multiple raceways are arranged on a stationary support structure, so that low dots of the raceways are defined in a surface of a connection in clockwise direction. A connection in counter-clockwise direction is set in a defined surface. Closed curve has no intersection points, and completely passes in an area of the defined surface.</p> |
