Abstract: A horizontally rotating driving apparatus is connected with a longitudinal rotating shaft and includes a frame, a rotating unit, multiple electromagnetic units and multiple sensor switch units. The frame is mounted on the rotating shaft and has an inner space formed inside the frame. The rotating unit is located in the inner space of the frame and is horizontally and rotatably mounted on the rotating shaft to form a rotation path. The electromagnetic units are disposed in the inner space of the frame and are arranged along the rotation path of the rotating unit. The sensor switch units are mounted in the frame and are disposed in the inner space of the frame at identical intervals. When one of the magnetic portions passes the sensor switch units, the sensor switch units sequentially control the electromagnetic units to start or to stop generating magnetic force and rotate the rotating unit.

Abstract: A gravity-assisted rotating driving apparatus is connected with a horizontal rotating shaft and includes a frame, a pendulum unit, at least one electromagnetic unit, and at least one sensor switch unit. The frame is mounted on the rotating shaft and has an inner space formed inside the frame. The pendulum unit is located in the inner space of the frame and is rotatably mounted on the rotating shaft to form a rotation path. The at least one electromagnetic unit is disposed in the inner space and is arranged along the rotation path. The at least one sensor switch unit is mounted in the frame and is disposed in the inner space. When the pendulum unit passes the adjacent sensor switch unit, the corresponding sensor switch unit controls the corresponding electromagnetic unit to start or stop generating magnetic force and to rotate the pendulum unit.
