  • Patent number: 10763690
    Abstract: A vehicle-side charging circuit for a vehicle with electric drive. The charging circuit comprises an AC connector, a controlled rectifier which is connected to the AC connector, an electric machine with at least one winding, a current converter which is connected to the electric machine, and an energy-storage-device connector. The at least one winding of the electric machine is coupled in series between the rectifier and the current converter. In an inverter mode the current converter is fed from the energy-storage device, and in a charging mode the current converter is from an external energy source via at least one series-connected winding of the electric machine and charges the electrical energy-storage device.

  • Patent number: 10027263
    Abstract: A method for detecting a fault in an electrical machine, e.g., a synchronous motor, a motor control unit for controlling an electrical machine, and a motor arrangement having such a motor control unit are disclosed. According to the method, rotation angle data are determined, which data are dependent on a rotation angle of a rotor of the electrical machine in the absence of the fault. In addition, additional data are determined and allow conclusions to be drawn on the fault. A fault is detected if the rotation angle data satisfy a first criterion and the additional data satisfy a second criterion.
