DRIVING DEVICE

A driving device (1) for driving a rotating shaft (21) includes a frame member (11), a magnetic pendulum unit (12), an electromagnetic unit (13) and a control unit (14). The magnetic pendulum unit (12) is rotatable about a center (112) of the frame member (11) through which a rotating shaft (21) extends and is connected co-rotatably to the rotating shaft (21). The electromagnetic unit (13) and the control unit (14) are spaced apart and are mounted on the frame member (11). The control unit (14) is configured to turn on and off the electromagnetic unit (13) to generate a magnetic force between the magnetic pendulum unit (12) and the electromagnetic unit (13) for facilitating rotation of the magnetic pendulum unit (12) and allow the magnetic pendulum unit (12) to pass by the electromagnetic unit (13), respectively.
