The generator - general information The BMW car of the 5th series has the generator of an alternating current. Depending on model of the car and its equipment generators of a nominal current 80 and 140 can be established And. The generator is actuated by the engine through maple a belt. The rotor and a stator of the generator have windings (at a rotor an excitement winding). The electric current to a winding of excitement 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 situation therefore in windings of a stator the electric current is formed. As the storage battery is charged by only a direct current, the alternating current will be transformed in constant by means of the rectifier being on a diode payment. The regulator of tension changes a charge current by inclusion and switching off of a current of excitement, depending on degree of a razryazhennost of the storage battery. Thus the regulator supports to constants working tension 14 In, irrespective of number of turns of the engine.
