Generator 9402.3701-06 — design features (Kalina 1118)

The vehicles are equipped with a three-phase alternating current generator type 9402.3701-06 with a built-in rectifier unit and an electronic voltage regulator, right-hand rotation (if you look from the drive side).

Technical characteristics of generator type 9402.3701-06

• Maximum output current at 14 V and 600 min, A - 85
• Adjustable voltage limits, V — 14.4-15.1
• Engine-to-generator gear ratio: 1:2.4

Stator 10 (figure 9.1) and covers 9 and 11 are pulled together with four screws. Rotor shaft 16 rotates in bearings 3 and 13, which are installed in the generator covers. Power supply to the rotor winding (excitation winding) is supplied through brushes and contact rings 4.

Three-phase alternating current induced in the stator winding is converted into direct current by the rectifier unit 1, attached to the cover 9. The electronic voltage regulator 7 is combined into one unit with the brush holder and is also attached to the generator cover 9.

The generator connection diagram is shown in the figure 9.2. The voltage for excitation of the generator when the ignition is turned on is supplied to the terminal "D+" of the regulator (terminal "L" of the generator) through the signal lamp 3 (see figure 9.1) battery discharge indicator located in the instrument cluster.

After starting the engine, the excitation winding is powered by three additional diodes installed on the generator rectifier block.

The "W" output of the generator is not used.

The operation of the generator is monitored by the battery charging indicator light located in the instrument cluster. When the ignition is turned on, the battery charging lamp should light up, and after the engine is started, it should go out if the generator is working properly. A bright or dimly lit battery charging lamp indicates a malfunction.
