10.4.1. Features of a design
On cars Chevrolet Lanos establish three-phase generators of an alternating current with electromagnetic excitation, with built in выпрямительным the block and an electronic regulator of pressure. On a generator shaft are located крыльчатка the fan and приводной a pulley. The shaft is established on the bearings of the closed type which are not demanding additional greasing during all service life. The shaft is resulted in rotation from a pulley of a cranked shaft поликлиновым by a belt.
Fig. 10.5. The electric scheme of the generator: 1 – an electronic regulator of pressure; 2 – an excitation winding; 3 – a contact ring of an anchor; 4 – выпрямительный the block; 5 – a winding of phases статора
On fig. 10.5 the
electric scheme of the generator of series CS of firm Delco Remy (Delphi) is shown. The conclusion In + is connected to the plug "plus" of the storage battery, and a conclusion L – with an alarm lamp of the category of the storage battery. Conclusions P, I and S are not used. The conclusion P is connected to a winding статора
and can be connected to a tachometre.
Recently there were many firms specialising on repair of import starters and generators. There it is possible to carry out diagnostics of faulty knot, to get spare parts for any model of the generator (starter), to receive the qualified consultation. If you are not assured that can repair the generator (starter) independently, there is a sense to address in such firm where repair of these knots will execute quickly, qualitatively and, as a rule, under the reasonable price. However on cars to the big run often happens more favourably to replace knot in gathering new, than to replace the failed details.
