Generator 37.3701: 1 - cover from the side of slip rings; 2 - rectifier block; 3 - rectifier block valve; 4 - screw fastening the rectifier unit; 5 - contact ring; 6 - rear ball bearing; 7 - capacitor; 8 - rotor shaft; 9 - conclusion «30» generator; 10 - conclusion «61» generator; 11 - output «IN» voltage regulator; 12 - voltage regulator; 13 - brush; 14 — a hairpin of fastening of the generator to a tension level; 15 - a pulley with a fan; 16 - pole tip of the rotor; 17 - remote bushing; 18 - front ball bearing; 19 - cover on the drive side; 20 - rotor winding; 21 - stator; 22 - stator winding; 23 - pole, rotor tip; 24 - buffer sleeve; 25 - sleeve; 26 - clamping sleeve.
The three-phase alternating current induced in the stator winding is converted into a direct current by a rectifier unit 2 attached to the cover 1. The electronic regulator 12 is combined into one unit with a brush holder and is also attached to the cover 1.
The generator connection diagram is shown in fig. 140. The voltage to excite the generator when the ignition is switched on is supplied to the terminal «IN» regulator through the control lamp 4, located in the instrument cluster. After starting the engine, the field winding is powered by three additional diodes installed on the rectifier unit. In this case, the current through the control lamp does not pass and it does not burn. The control voltage is applied to the output «B» controller directly from the terminal «30» generator. Conclusion «W» does not have a label. Grid 13 is connected to it (see fig. 139).
