Method for operating a drive system for a work machine, drive system and work machine

A drive system for a work machine, comprising:

• a travel drive having a first electric motor;
• a work drive having a second electric motor;
• a common electric energy store configured to operate the first and the second electric motors, the common electric energy store being associated with the travel drive and the work drive,
• wherein the first electric motor is configured to be operated in generator mode to produce braking power of the travel drive;
• and
• a friction brake,
• wherein electric power is produced in generator mode,
• wherein a controller of the drive system is configured to supply the electric power completely or partly to the common electric energy store and/or to the second electric motor depending on a state of the common electric energy store, and
• wherein the friction brake limits the electric power that can be produced in the generator mode if it exceeds the total electric power that can be received in total by the common electric energy store and by the second electric motor.
