Abstract
A method for detecting a fault in a generator unit that has an electrical machine including a rotor winding and a stator winding and a rectifier connected thereto, via which the electrical machine is connected to an electrical system of a motor vehicle. Whether or not the fault exists is determined as a function of an excitation current traversing the rotor winding of the electrical machine and as a function of a setpoint value of the excitation current.

A method for detecting a fault in a generator unit, the generator unit including an electrical machine, and a rotor winding, a stator winding, and a rectifier connected to the electrical machine, via which the electrical machine is connected to an electrical system of a motor vehicle, the method comprising:
- determining whether or not the fault exists as a function of an excitation current traversing the rotor winding of the electrical machine and as a function of a setpoint value of the excitation current.
A method for securely operating a generator unit, the generator unit including an electrical machine, and a rotor winding, a stator winding, and a rectifier connected to the electrical machine, via which the electrical machine is connected to an electrical system of a motor vehicle, the method comprising:
- recognizing a fault exists as a function of an excitation current traversing the rotor winding of the electrical machine and as a function of a setpoint value of the excitation current;
- and
- based on recognizing the fault exists, one of:
- (i) reducing an amount of excitation current, or (ii) pulsing the excitation current.
A generator regulator that is adapted for securely operating a generator unit, the generator unit including an electrical machine, and a rotor winding, a stator winding, and a rectifier connected to the electrical machine, via which the electrical machine is connected to an electrical system of a motor vehicle, the generator regulator adapted to:
- recognize a fault exists as a function of an excitation current traversing the rotor winding of the electrical machine and as a function of a setpoint value of the excitation current;
- and
- based on recognizing the fault exists, one of:
- (i) reduce an amount of excitation current, or (ii) pulse the excitation current.
A non-transitory machine-readable storage medium on which is stored a computer program for securely operating a generator unit, the generator unit including an electrical machine, and a rotor winding, a stator winding, and a rectifier connected to the electrical machine, via which the electrical machine is connected to an electrical system of a motor vehicle, the computer program, when executed by a computer, causing the computer to perform:
- recognizing a fault exists as a function of an excitation current traversing the rotor winding of the electrical machine and as a function of a setpoint value of the excitation current;
- and
- based on recognizing the fault exists, one of:
- (i) reducing an amount of excitation current, or (ii) pulsing the excitation current.
