Removal and installation of the generatorLongitudinal section of the generator
Scheme of connection of windings of the generator
On the considered cars the synchronous generator of alternating current with the built-in rectifier is used.
All generators which are essentially used to a complete set (see Specifications) are arranged equally. The partial longitudinal section of the generator is presented on an illustration, the scheme of connection of windings - on an illustration below.
The case of the generator consists of two covers (forward and back), the bolted three long through M5. In the case the stator is not movably fixed. Three wire windings connected among themselves by a triangle are reeled up on the isolated metal plates of the stator. Windings of the stator are connected to nine vypryamitelny silicon diodes placed on payments and arms in the generator case. Diodes carry out straightening of the alternating current generated in windings.
In both covers of the case of the generator it is placed on the ball bearing in which the rotor shaft is put. On a shaft of a rotor the magnets of a characteristic "klyuvoobrazny" form covering an excitement winding are fixed. On the same contact rings are established to a shaft. Rings are isolated from a shaft and connected to excitement winding conclusions.
The sprung coal brushes rest against contact rings. One of 5.shchetok is connected to the D+ plug, the second - to the D-plug. Wires from both plugs are removed outside through a back cover. At inclusion of ignition when the engine is not started yet, the following electric chain is powered: the positive plug of the battery - contacts of the switch of ignition - a control lamp - tension regulator - a winding of excitement of the generator - weight. At the same time the control lamp in an instrument guard of the car joins.
Upon completion of start of the engine when the frequency of rotation of a bent shaft exceeds 900 rpm, the generator is excited and begins to develop the alternating current straightened then diode assembly. On the plug D + at the same time there is tension and as there is no difference of potentials on a control lamp any more, it dies away. Current comes to an excitement winding via three diodes (6) and the regulator of tension. The diodes called by excitement diodes work similar to diodes (4) and (5), with only that difference that their loading is only the winding of excitement and the regulator of tension in view of what they it is less by the size and do not need heat-removing radiators.
Current between the generator and the rechargeable battery can flow only in one naprvleniye - from the generator to the battery. Into the opposite side it is not allowed by diode vypryamitelny assembly.
The size of tension created by the generator is regulated by change of current of excitement in a rotor winding. This function is performed by tension regulator.
