Generators of alternating current are installed in cars. Depending on model and the electric equipment installed on the car generators of various power can be installed. At installation of the additional electric equipment check that there was enough power of the generator for power supply of this equipment.
The drive of the generator is carried out by a maple belt from a bent shaft of the engine.
The generator represents the three-phase synchronous electrical machine with electromagnetic excitement. For transformation of alternating current in constant the rectifier on diodes is built in the generator. Tension is regulated by the built-in microelectronic regulator of tension.
During the operation of the generator the electric current proceeding on a winding of excitement creates a magnetic flux around rotor poles. At rotation of a rotor under each tooth of the stator passes the southern, the North Pole of a rotor and a working magnetic flux passing through stator teeth changes in size and tension. This variable magnetic flux creates the electromotive force in a stator winding. The wedge-shaped form of polar tips of a rotor is picked up in such a way that allows to receive a form of curve electromotive force close to sinusoidal.
With a high frequency of rotation of a rotor of the generator when tension of the generator becomes more, than 13,6-14,6 B, the regulator of tension is locked and current does not pass through a winding of excitement. Tension of the generator falls, the regulator opens and again passes current through an excitement winding. The frequency of rotation of a rotor of the generator is higher, the time of the locked condition of the regulator is more, therefore, the stronger tension at the generator exit decreases. Process of locking and unlocking of the regulator happens with high frequency therefore fluctuations of tension at the exit of the generator are not noticeable, and the constants supported at the level of 13,6–14,6 Century can almost consider it.
When checking the generator, and also at operation of the car it is necessary to follow a number of simple rules not to put the generator out of action:
Not to allow operation of the generator with the rechargeable battery disconnected from a generator clip. Without rechargeable battery in onboard network of the car there are dangerous impulses to a perenapryazha a niya at shutdown of any consumers of the electric power. This pulse an overstrain can put the electronic equipment of the car, including the regulator of tension and diodes of the vypryamitelny block of the generator out of action.
Not to check operability of the generator for a spark, even short-term connection of a plus clip of the generator with weight. At the same time via diodes considerable current proceeds and they damage ся. It is possible to control generator tension only the voltmeter.
Minus of the rechargeable battery has to connect always to the mass of the car, and plus to be connected to a generator clip. Wrong (return) turning on of the battery will immediately cause passing of the raised current via generator diodes, and they will fail.
Not to check diodes more than 12 V or the megohm meter as it has tension, too high for diodes, and they when checking will be punched (there will be a short circuit). When checking isolation of an electrical wiring the megohm meter it is necessary to disconnect all wires from the generator.
It is necessary to disconnect all wires from the generator and from the accumulator at electric welding of any details of a body.
To check chains and knots of electric equipment and to eliminate malfunctions it is necessary at the idle engine and the disconnected rechargeable battery.
