Toyota RAV4>> Electric equipment>> Generator>> General information
Cars equip with generators of an alternating current. Depending on model and the electric equipment established on the car generators of various capacity can be established. At installation of additional electric equipment check, that capacities of the generator was enough for a food of the new consumer.
The drive of the generator is carried out by a poliklinovy belt from a cranked shaft of the engine.
The generator represents the three-phase synchronous electric car with electromagnetic excitement. For transformation of an alternating current in constant the rectifier is built in the generator on diodes. Tension is regulated by the built-in microelectronic regulator of tension.
At operation of the generator the electric current proceeding on a winding of excitement, creates a magnetic field round rotor poles. At rotor rotation under stator coils alternately pass rotor poles, the magnetic stream changes on size and the direction and creates in a stator winding an electromotive power.
At high frequency of rotation of a rotor of the generator when tension of the generator becomes more than 13,6–14,6 In, the regulator of tension is locked and the current does not pass through a winding of excitement. Tension of the generator falls, the regulator opens and again passes a current through an excitement winding. The frequency of rotation of a rotor of the generator is higher, the it is more time of the locked condition of a regulator, therefore, the more strongly tension on a generator exit decreases. Process of locking and unlocking of a regulator occurs to high frequency therefore tension fluctuations on an exit of the generator are imperceptible, and it is almost possible to consider it to the constants supported at level of 13,6-14,6 Century.
At generator checks, and also at operation of the car observe the following security measures not to put the generator out of action:
Do not allow operation of the generator with the disconnected storage battery. At operation of the generator with the disconnected battery in an onboard network of the car there are tension increases at shutdown of any consumers of the electric power, bringing to failure of the electronic equipment of the car, including a regulator of tension and the vypryamitelny block of the generator.
Do not check operability of the generator on "spark", even short-term connection of a "plusovy" conclusion of the generator with in "weight". Thus via the vypryamitelny block the considerable current and its diodes proceeds are damaged. Check tension of the generator only the voltmeter.
The "minus" plug of the storage battery always should incorporate to "mass" of the car, and "plusovy" to be connected to a generator conclusion. The wrong (return) connection of the battery will sharply raise a current passing through diodes of the generator, and they will fail.
Do not check diodes tension more than 12 in or megommetry as it has too high tension for diodes. In this case at check diodes will be punched (there will be a short circuit). At check of isolation of electroconducting by an ohmmeter disconnect all wires from the generator.
Surely disconnect all wires from the generator and the storage battery at electric welding of knots of details of a body.
Check chains and knots of electric equipment and eliminate malfunctions at the idle engine and the disconnected storage battery.
