The generator - the general data Car BMW of 5th series has the alternating current generator. Depending on model of the car and its equipment generators of a nominal current strength 80 and 140 can be established And. The generator is set in motion by the engine through клиновой a belt. And статор the generator windings (at a rotor an excitation winding) have a rotor. The electric current to a winding of excitation of a rotor arrives through brushes and contact rings and creates an electromagnetic field in the generator. The electromagnetic field of a rotor at its rotation changes position therefore in windings статора the electric current is formed. As the storage battery is charged only by a direct current, the alternating current will be transformed in constant by means of the rectifier which is on диодной to a payment. The pressure regulator changes a current of a charge by inclusion and deenergizing of a current of excitation, depending on degree разряженности the storage battery. Thus the regulator supports to constants working pressure 14 In, irrespective of number of turns of the engine.
