System of a load - general information and measures of security

In the cars found the creator of the alternate current it is in use. During the installation of the check of additional electric equipment that there was enough power of the creator to provide new consumers of the electric power.

The walk of the creator is executed by a belt of the form of wedge of an end of inclination of the motor.

The creator represents the synchronous electric machine of three phases with excitement eletromagnética. For the transformation of the current alternated in the constant one the diode rectifier is built in the creator. The agreement of the tension is executed by the built regulator.

During the operation of the creator the electric current that continues with an excitement curve creates a magnetic flow around rotor poles. In the moment of the rotation of a rotor there is a periodic modification of his magnetic poles below each tooth of the fixed part of the electric motor, consequently, the magnetic flow that passes by teeth, continuously it is modified in size and tension. This variable magnetic flow was believing the force eletromotora (EMF) in a curve of fixed part of the electric motor. The form of the form of wedge of polar hints of a rotor is caught so that it allows to receive near to sinusoidal the form of the curve EMF.

With a high frequency of the rotation of a rotor when the tension of production of the creator begins when 13,6 is exceeding ÷ 14.6 B, the regulator of the tension is locked and the current does not pass by an excitement curve. When the tension lessens, the regulator opens again, supplying the freedom of a transmission of the current through an excitement curve. The frequency of the rotation of a rotor is higher, the longest the regulator remains locked and, this respectively tension in the moment of the strongest reductions of creator's exit. The closure process and desprendimento of the regulator it happens with the high frequency, therefore, the production fluctuations remain the almost imperceptible and the constant ones supported at the level of 13,6 14.6 century ÷ can consider the tension of the creator.

The system of the load does not demand the periodic service, nevertheless the check of a state and substitution of a belt of driving of the creator, the battery recarregável and his electrical system that is necessary to do in a regular base according to the time-table THAT (to see the Chief Nastroyki and the regular maintenance of the car).

In the moment of the inclusion of the ignition in a devices combination To/L will illuminate quickly a load (to see the Front Administrations and the methods of the operation). If the lamp not if desconectar a little subsequent time after the implementation of the launch of the motor or to illuminate in the course of the functioning of the last one, checks a condition of component ones of the system of a load. The refusal of the activation of a lamp in the moment of the inclusion of the ignition testifies to his exit out of operation, damage of the corresponding electrical system or violation of the usefulness of the functioning of the creator (including the interval of a belt of driving).

The security measures in the service of the creator

• Do not call - of the battery or the regulator of the tension in the work motor;
• Do not close the capture of excitement of the creator or the thread was concentrated in him in the weight;
• Do not confuse an order of the connection of an electrical system of the regulator of the tension;
• Remember that the connection of the regulator of the tension closed in the weight leads to an immediate exit he out of the operation;
• Never remove the creator in the connected battery;
• Do not confuse the polarity of the connection of the battery recarregável;
• Never use the instruments of measuring of the tension or a few clothes with samples of embroidery of lamp joined to the net of house (110/220 B) checking the electric equipment of side;
• When it checks a condition of diodes do not give in them the voltage any more than 12 V and it does not use the meters megohm what also have the high tension of exit, - the diodes exhaustion will lead to the short circuit. Remember that checking the isolation of an electrical system through the meter megohm the whole electrical system of the creator is necessary desconectar;
• In the moment of the load of the battery recarregável without removal of the trace of the car link that both wires if desconectaram of him. Do not confuse the polarity of the connection of the porter;
• Before executing in the car of any electrowelding works they do not forget of desconectar an electrical system of the creator and the battery recarregável;
• It carries out any control of chains and the knots of the electrical system of side in the idle motor and the battery recarregável off;
• Remember that the violation of the polarity of any connection is accompanied by the risk of irrevocable failure of the rectifier and regulator of the tension of the creator.
