Preferably, the output shaft 6 extends from one side of the fourth electromagnetic clutch 4 and is arranged opposite to the motor 13, so as to be conveniently connected with the power transmission unit.
In this embodiment, the diameter of the flywheel is greater than the diameter of the transmission wheel to provide a larger moment of inertia, so as to realize the effect of outputting torque outwards by means of the rotation of the flywheel itself, and the torque of the electromagnetic clutch can be adjusted to adapt to flywheels with different sizes. The driving wheel adopts a belt pulley, and the first power transmission system and the second power transmission system adopt a belt for transmission.

Then, the control system turns off the first electromagnetic clutch 1 and the fourth electromagnetic clutch 4, turns on the second electromagnetic clutch 2 and the third electromagnetic clutch 3, at this time, the first flywheel 11 is in high-speed rotation, and after the third electromagnetic clutch 3 is turned on, the first flywheel 11 and the third electromagnetic clutch 3 are attracted together, and because the third electromagnetic clutch 3 and the output shaft 6 are fixedly connected, the rotational inertia of the first flywheel 11 is output outwards through the output shaft 6. Meanwhile, after the second electromagnetic clutch 2 is switched on, the rotation of the input shaft 5 can drive the second transmission wheel 8 to rotate, the second transmission wheel 8 drives the fourth transmission wheel 10 and the second flywheel 12 to rotate, and because the fourth electromagnetic clutch 4 is in a switched-off state at the moment, the second flywheel 12 only idles on the output shaft 6 and reaches a preset rotating speed.
Because the first flywheel 11 outputs torque outwards and no other power is added, the rotating speed of the first flywheel 11 can be rapidly reduced within a few seconds, at the moment, the second electromagnetic clutch 2 and the third electromagnetic clutch 3 are switched off again, the first electromagnetic clutch 1 and the fourth electromagnetic clutch 4 are switched on, the input shaft 5 drives the first transmission wheel 7 to rotate, then the first flywheel 11 is accelerated to a specified rotating speed, meanwhile, the second flywheel 12 starts to output torque outwards by means of self inertia power, the operation is repeated, large-torque output can be realized by the aid of the motor 13 with small torque, and when the two groups of clutches are switched, the first flywheel 11 or the second flywheel 12 are in a moving state rather than a static state, so that resistance to be overcome for the motor 13 is very small, the motor 13 can be well protected, and the service life of the motor 13 is prolonged.
