If the motor clutch 91 is opened, the motor generator 92, which works as an electric motor, can then drive the belt drive and thus the crushing unit 40 via the closed crushing unit clutch 93 and the drive shaft 46.
  • the motor generator 92 If the motor generator 92 is to be operated in generator mode, the internal combustion engine 41 is activated and the motor clutch 91 is closed. As a result, the motor-generator shaft 92.1 is driven by means of the internal combustion engine 41 and the motor rotor 92.6 is set in rotation. Due to the electromagnetic field acting between the motor rotor 92.6 and the motor generator 92.8, the current generated in the motor stator 92.8 is derived via the connection 94. In this operating state, either the crushing unit clutch 93 can be opened or it is also conceivable that the crushing unit 40 is operated when the crushing unit clutch is closed.
