METHOD FOR DETECTING AN ERROR IN A GENERATOR UNIT
A method for detecting an error in a generator unit which has an electric machine (100) with a rotor winding (110) and a stator winding (120) and a rectifier (130) connected thereto, via which rectifier the electric machine (100) is connected to an electrical system (150) of a motor vehicle, the exc...

| description | A method for detecting an error in a generator unit which has an electric machine (100) with a rotor winding (110) and a stator winding (120) and a rectifier (130) connected thereto, via which rectifier the electric machine (100) is connected to an electrical system (150) of a motor vehicle, the excitation current (IE) flowing through the rotor winding (110) of the electric machine (100) being plotted and it being concluded that there is an error in the generator unit depending on whether a frequency component (A) of a frequency spectrum of the plot of the excitation current (IE) in a frequency range above a lower speed limit (SW) is larger than a threshold value (S). |
