The 24V power adapter 15 uses one phase of the air switch 11 as a live wire and the ground wire of the air switch 11 as a neutral wire.

[0031] When the flywheel 4 is storing energy, the electric energy is sequentially supplied to the motor 6 through the air switch 11, the contactor 12 and the power converter 13, so that the motor 6 rotates with electricity, and the motor 6 drives the flywheel 4 to rotate, thereby realizing energy storage.

[0032] An emergency stop switch 14 is provided on the front side of the left electric control box 2 , and the emergency stop switch 14 is connected to the contactor 12 and is used to control the power-off action of the contactor 12 .

[0033] The right electric control box 3 is provided with a power collector 18 , a three-hole socket 16 , and an industrial control touch all-in-one machine 1 .

[0034] The three-hole socket 16 uses one phase of the air switch 11 as the live wire and the ground wire of the air switch 11 as the neutral wire. The industrial control touch all-in-one machine 1 is connected to the three-hole socket 16 to realize power supply.

[0035] The power collector 18 is electrically connected to the power converter 13; when releasing energy, the power collector 18 is used to collect the power output of the motor 6, and the power collector 18 is connected to the load resistor 19 through a wire. The air switch 11 supplies power to the power collector 18 through a 24V power adapter 15.

Magnets with opposite magnetic properties are provided at the other ends of the first brake arm 52 and the second brake arm 53. When the coil is energized to generate a magnetic field in the iron core, the other ends of the first brake arm 52 and the second brake arm 53 can be moved away from each other, thereby braking the flywheel 4.

[0039] The working principle of this embodiment is:

[0040] When the industrial control touch all-in-one machine 1 is operated so that the mains can supply power to the motor 6 through the power converter 13, the motor 6 can drive the flywheel 4 to rotate, thereby realizing energy storage of the flywheel 4. After energy storage is completed, the industrial control touch all-in-one machine 1 is operated again so that the power supply relationship between the mains and the motor 6 is disconnected, and the motor 6 is connected to the power collector 18 by switching the power converter 13.
