摘要： A method for braking a motor (24,25) in a high lift system (100) of an aircraft, the high lift system (100) comprising a central power drive unit for moving high lift surfaces (36) arranged at a wing through providing rotational power by means of a transmission shaft (30,32) to a plurality of drive stations (34) operably coupled with the high lift surfaces (36); which power drive unit (22) is operatively coupled to a controller (160) and comprises at least one electric motor (24,25) coupled therewith. The method includes determining a braking requirement for the at least one electric motor (24,25), measuring at least one of a current command to the motor (24,25) and a current speed and direction of the at least one electric motor (24,25), based on the braking requirement, applying a braking command to the at least one electric motor (24,25), and reducing the braking command as the at least one electric motor (24,25) comes to rest.
