  • Patent number: 10804832
    Abstract: The invention relates to a control system and to a method for operating a synchronous machine. In particular, the synchronous machine is controlled on the basis of a rotor angle that was determined by means of a sensorless rotor-angle detection method. In order to check the reliability of the rotor angle determined without sensors, the difference value between the rotor inductances in the q direction and in the d direction is monitored. If said difference value falls below a limit value, this indicates possible instabilities in the determination of the rotor angle.

  • Patent number: 10788527
    Abstract: 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).

  • Patent number: 9214882
    Abstract: Determining the rotor angle of a synchronous machine. In one aspect, the invention provides a method that includes generating a multiplicity of pulse-width-modulated drive signals for the phases of an inverter feeding the synchronous machine depending on a voltage to be fed into the synchronous machine, and applying a first phase shift to one or more of the multiplicity of pulse-width-modulated drive signals, so that the duration of the switching states of the inverter is extended in order to generate a first switching pattern for the phases of the inverter. The method also includes applying a second phase shift to one or more of the multiplicity of pulse-width-modulated drive signals for generating a second switching pattern, selecting one or more of the first and second switching patterns, determining one or more of neutral point potentials at the neutral point of the synchronous machine, and calculating the rotor angle of the synchronous machine.
