A rotating window includes a circular base member, a transparent window, and a
magneto-conductive element, which are assembled into an
electric motor device. By this rotating window, area of transparent region of the transparent window is increased, an outer
diameter of a central shaft hole is decreased, and a support bracket is designed as an I-shape or a half I-shape, thereby largely decreasing barriers to the transparent window, allowing a user to conveniently see through scenery or objects at one side of the transparent window without a dead angle. In case that the rotating window is hit by objects and rotates eccentrically, an air gap of the motor disappears, and an entire frame of the rotating window will be absorbed magnetically to the
magneto-conductive element, thereby improving safety to people and objects.
