ABSTRACT:
The method of regulating a motor vehicle three-phase generator for operation in an overexcited range includes determining a temperature of the generator by a temperature-determining device provided in a voltage regulator circuit for the generator, supporting the housing of the voltage regulator on one of the generator component parts, reducing an excitation current of an excitation coil of the generator to keep the temperature of the generator below a predetermined maximum temperature when a generator speed is between a first generator speed threshold and a second generator speed threshold and increasing the excitation current of the excitation coil of the generator above the nominal value of the excitation current without consideration of the determined temperature, when the generator speed exceeds the second predetermined generator speed threshold and is below the first predetermined generator speed threshold.
