VORRICHTUNG UND VERFAHREN ZUR REGELUNG EINES FAHRZEUG-DREHSTROM-GENERATORS

摘要

To ensure an optimal supply of energy to the electrical system from a motor vehicle three-phase alternator, the excitation current is increased above the rated excitation current when the alternator rotates at low speeds, reduced at medium rotational speeds and increased again above the rated excitation current at high rotational speeds. As the temperature in the regulator itself is measured and the regulator is fastened to an alternator component which becomes particularly hot, the moment at which the alternator reaches a maximum permissible temperature can be ascertained in time. The excitation current is then reduced sufficiently for the maximum temperature not to be exceeded.
