Abstract
A passive drive motor is disclosed. A stator assembly is connected to a base. A rotating shaft is rotatably connected to the base. A rotor assembly is connected to the rotating shaft. The rotor assembly interacts with the stator assembly to rotate the rotating shaft. A first metal disk is rotated by the rotating shaft. At least one first magnet pair is disposed on the first metal disk. A second metal disk opposes the first magnet pair. When the rotating shaft rotates to drive the first metal disk to rotate, the first magnet pair disposed on the first metal disk magnetically interacts with the second metal disk, driving the second metal disk to rotate with respect to the first metal disk.
