Abstract
A method for operating a fuel feed pump, the fuel feed pump having a pump system and an electrically commutated electric motor, the pump system being drivable by the electric motor, includes: detecting fluctuation in circular motion of the pump system over a rotational speed of the pump system to obtain a value of the fluctuation; standardizing the detected value of the fluctuation to obtain a standardized valise; and in a case in which a predefinable limit is exceeded by the standardized value, limiting a gradient of change in the rotational speed of the pump system.
