7.4. Creator
The cars Hyundai are equipped of creators of the alternate current. Depending on model and creators of modification of several power it can be installed. The power is specified in the plate of identification of the creator.
The creator with the built regulator of the tension loga collecting of the battery recarregável what lights the battery recarregável and a control lamp with the driving.
The creator is equipped of six built diodes (three "positives" and three "negation") transforming current alternated to the constant one. Therefore, for a conclusion In the creator the continuous current happens.
Besides, of collecting developed by the creator one regulates the tension of the current for the system of control of the tension of the battery recarregável. The component principals of the creator are the rotor, the fixed part of the electric motor, the block of vypryamitelny, you brush, loads and a pulley of the transmission for strap. The electronic regulator of the tension is built in the brush bearer.

PREVENTION
During the installation of the check of additional equipment there is enough power of the ancient creator; if necessary the creator and the battery establishes more powerful.
|
A belt sets the creator in motion of an inclination end for the side. The creator's rotor with a curve of great excitement in a motionless curve of the fixed part of the electric motor with a frequency that two times exceeds the frequency of the rotation of an end of inclination of the motor.
In brushes from coal and rings of contact of the creator through a curve of product of current of excitement of excitement. The magnetic field is created.
The position of the magnetic field regarding a fixed part of the electric motor that it rolls up constantly is modified according to the direction of the rotation of a rotor. Thanks to him in a curve of the fixed part of the motor electric that periodic electric current develops.
The battery recarregável can be accused only with a continuous current, the alternate current is going to be turned into the constant one in the rectifier in a payment of diode of the creator. The regulator of modifications of tension that are discharged current inclusion and call of excitement current depending on degree of state of load of the battery. At the same time the regulator of the tension supports the tension of battery to constant equals of 14 V independent of the frequency of the rotation of an end of inclination of the motor.
The security measures in the moment of repair and service of the creator
Before executing any work in the system of the load of the battery recarregável, it is necessary to know the next measures of security.
During the works with elements of the system of the electric equipment in a driving compartment certainly desconectam the thread of pesos of the negative capture of the battery recarregável.
|
PREVENTION
A lack of interest of wire of the negative capture of the data of battery you were re-overdoing of the memory of one unity of electronic control of the system of the injection and a protective code of the radio-receiver they are put out. If the radio-receiver is encoded, before the stoppage it is necessary to convince that the protective code is known to you. Without him after the connection of being able the receiver will not be lit.
|
Do not mix threads of the regulator of the tension and the creator. Before the stoppage they mark us with an insulating tape.
Do not call - of the battery recarregável or the regulator of the tension in the work motor.
Do not remove the creator in the battery recarregável connected.
When it executes electrowelding works certainly it calls - of the battery recarregável.
Check of technical condition of the creator
Check of failure of power in a wire of production of the creator

The scheme of the check of the failure of power in a wire of production of the creator is shown in the fig. 7.4.
The capture of the battery executes the check for the definition of the usefulness of a wire between a conclusion In the creator and it + recarregável in the power failure in a wire.
Install a key in the ignition lock in his provision (it is put out).
|
TO OBSERVE
The definition of the confidence of connections of a wire checking there do not call both conclusions and his connections.
|
One annexes more the wire ("+") from the digital voltômetro to a conclusion In the creator, and one less the wire ("-") of the voltômetro to + the capture of the battery recarregável.
Read aloud indications of the voltômetro in the motor of work, the included headlights, the electric supporter of the hall and other consumers of the electric power.
The tension in the voltômetro will be the 14th century.
If the measured tension disagrees over 0,3 B, then it indicates the bad functioning of the driving. Check the wires that join a conclusion In the creator for an insertion fuse to + the capture of the battery recarregável.
Check the driving to be weakened of connections or modification of the color of a wire of overheating. Remove the bad functioning and the repeated check.
After the check they let the work of motor to us waste time, soon they put lighthouses out, electric supporter of the hall and other consumers of the energy, put the ignition out.
Check of current of return of the creator
An inspection is executed for aims of the definition of the complaisance of the current of the return of the creator to the nominal tariff.
|

|
Before the check they carry out the next checks and if necessary bad functioning removes.
Check the usefulness of the battery recarregável installed in the car.
|
TO OBSERVE
Checking the current of the return of the creator to battery recarregável it has to be unloaded partially. In the completely loaded battery the result of the check will be inaccurate because of the insufficient load of the creator.
|
Check a tension of belt of creator's walk.
Install the key of ignition in his provision (it is put out).
Desconecte a wire "of less" the capture of the battery recarregável.
Desconecte a wire of a conclusion In the creator.
Annex the ampermeter of a continuous current (with a measurements limit 0-100 A) constantly to a conclusion "in" and to the wire of production left a creator. "-" the ampermeter annex a wire of a conclusion to the production wire off.
|
TO OBSERVE
Because of the great current confiantemente they delay both connections. Do not use clips as "crocodile".
|
Annex the voltômetro (with a limit of measurements of 0-20 V) to a conclusion "in" and I "weigh": "one more" the wire ("+") from the voltômetro — to a conclusion In the creator, and "one less" the wire ("-") – is fiável "to the weight".
Annex a tacômetro of the control of the frequency of the rotation of an end of inclination of the motor, annex a wire of the negative capture of the battery.
Leave a hood of unbuttoned monk.
One secures that the voltômetro shows the tension of the battery recarregável. If the voltômetro shows 0, it breaks then of wire between a conclusion In the creator and the battery - the capture, the burn - out of an insertion fuse or bad connection with "the weight" are the possible reasons.
Launch the motor and include lighthouses.
There lights the ray of driving of lighthouses and the supporter of a heater in the highest speed, agudamente increase the frequency of the rotation of an end of inclination up to 2.500 minutes 1 and register the very current of the return of the creator in the ampermeter.
The indication of the ampermeter will exceed the very permissible value (see down). If it is lower in a wire of useful production of the creator, remove the creator of the car and check it.
The very permissible current of return of the creator, E, not less:
creator 70 A..... 49,0
creator 90 A..... 63,0
|
TO OBSERVE
The nominal tariff of the current of the return is specified in the plate one concentrated in a creator who fits, therefore, in the current value of the current of the return it can be differentiated of the nominal one. In this case they include lighthouses to unload the battery recarregável.
|
In the ending of the check of the current of the return they reduce the frequency of the rotation of the motor to waste time and put the ignition out.
Desconecte a wire of the negative capture of the battery recarregável.
Desconecte the ampermeter, the voltômetro and a tacômetro of control.
Annex a wire of production to a conclusion In the creator.
Annex a wire to the negative capture of the battery recarregável.
|
TO OBSERVE
After the launch of the current of load of motor quickly lessens. To obtain the very true value of the current the Repairs affirmed in top that it must be executed, passing so somewhat possible all that the time.

– check the usefulness of the battery recarregável installed in the car;
– check a tension of belt of creator's walk.
Install the key of ignition in his provision (it is put out).
Desconecte a wire "of less" the capture of the battery recarregável.
The digital voltômetro annexes it
to the conclusion of "S (L)" of the creator and to "consider" ("one more" the wire ("+") the voltômetro — to a conclusion of "S (L)" of the creator, and "one less" the wire of the voltômetro ("-") – "at least" the capture ("-") the battery recarregável).
Desconecte a wire of production of the creator of a conclusion "in".
Annex the ampermeter of a continuous current (with a measurements limit 0-100 A) constantly to a conclusion "in" and to the wire of production left a creator. "One less" ("-") of the ampermeter they annex the wire to the production wire off.
Annex a tacômetro of the control of the frequency of the rotation of the motor and the capture of the battery annexes a wire "at least".
Include the ignition and be convinced that the voltômetro shows the tension of the battery recarregável. If the voltômetro will show 0, then the break of a chain between a conclusion of "S (L)" of the creator and "it more" the capture ("+") batteries or burn - out of an insertion fuse is the reason.
Launch the motor, put out lighthouses and all the consumers of the electric power.
Increase the frequency of the rotation of an end of inclination approximately up to 2.500 minutes 1 and It registers the indication of the voltômetro in the reduction of the current of the return of the creator to 10 or less.
