Generator specifications (Audi 80 B2)

The cars were equipped with a three-phase alternating current generator of the Bosch brand, type K1 14V, with a built-in rectifier block on nine valves (six rectifier diodes and three additional diodes) and an electronic voltage regulator. The stator windings are connected in a star. The rotor consists of an excitation winding, two contact rings are pressed onto the rotor shaft. The generator is cooled through the holes in the covers and by a fan mounted on the drive pulley. The generator is driven by a V-belt.

Maximum output current, A: 45 or 55.

Generator charging current with a return current of -15 A at an engine crankshaft speed of 3000 rpm, A 30.

Nominal voltage, V: 14.

Rotor speed at the moment the charging current starts to flow to the battery, with a terminal voltage of 14 V and steady state, rpm: 1000.

Rotor winding resistance at 20°C, Ohm: 2.8-3.0.

Resistance of the stator winding between different terminals at 20°C, Ohm: 0.10-0.11.

The limits of regulated voltage at a rotor speed of 3000 rpm and a discharge current of 45 A, V: 12.5-14.5.

Height of new brushes, mm: 10.

Minimum protrusion of brushes from the brush holder, mm. 5.

Generator drive belt

Brand and type: Kleber Venuflex AV 10 940; Dauso 10 375.

The normal deflection of the belt when pressing hard with the thumb on the middle of the branch should be within 10-15 mm.
