The motor and generator are integrated to realize the reciprocal operation of electric power generation / power generation, and can work in There are two states of electric and power generation, which simplifies the structure of the flywheel energy storage system.

The invention refers to a dynamic balance adjusting device of a rotary drum for plates with different sizes of a direct plate setter. The invention discloses an automatic dynamic balance device of a direct plate setter. The automatic dynamic balance device comprises a rotary drum and a balance block supporting and guiding device arranged on the rotary drum; the balance block supporting and guiding device comprises an end cover (73) arranged at the side face of the rotary cylinder and a slide block supporting ring (74); and balance blocks (78) are clamped between the end cover (73) and the slide block supporting ring (74). The automatic dynamic balance device further comprises a balance block driving system, comprising an electric motor (106) and a push rod (100). Through fixing the balance blocks on two end faces of the rotary drum, the problem of dynamic balance of the rotary drum caused by the plates with different sizes is solved, so that the vibration amplitude of the rotary drum in the high-speed rotation is reduced; and due to the fact that the dynamic balance is automatically realized, the work time is decreased, and the working efficiency of the direct plate setter is increased.
