The vehicle is equipped with a three-phase alternating current generator with electromagnetic excitation, a diode rectifier unit and a built-in voltage regulator.
The generator 1 is driven by a poly-V belt for driving auxiliary units 2 from the crankshaft pulley 3.
The generator consists of a rotor, a stator, a rectifier unit, a brush assembly with a voltage regulator and two covers. A pulley is installed on the rotor shaft. To cool the generator parts, ventilation holes are made in its covers, and an impeller is made on the rotor on the side of the front cover.
The stator has a three-phase winding connected in a "star". The winding terminals are soldered to the rectifier unit. The rectifier unit is installed under the generator casing together with the brush assembly and voltage regulator.
The rotor contains an excitation winding, the terminals of which are soldered to two contact rings.
The generator rotor shaft rotates on two ball bearings. The front bearing is pressed into the front cover of the generator, and the rear bearing is pressed onto the rotor shaft and held in place by the rear cover of the generator.
The voltage regulator is contactless, electronic, and combined with a brush unit in a common non-separable housing. The voltage regulator is controlled by the electronic engine control unit (ECU). The brushes are carbon and spring-loaded.
Note: The generator is a difficult-to-disassemble structure, so in case of its failure, it is recommended to contact a specialized workshop or replace the generator assembly. This Chapter describes only those operations that do not require special skills or equipment.
Recommendation. If the battery charge indicator light comes on on the instrument panel, do not rush to immediately remove the generator for repair or replacement. First, make sure that the fault is caused by a failure of the generator itself, and not by a failure of the wiring in its electrical circuit or a loose drive belt (see below, "Diagnosing Generator Faults").
