The starter mounted on the car engine is a four-pole DC motor with series excitation and a traction relay. On - 75 A.
Rotor winding resistance at 200 C: 2.8–3.0 Ohm.
Stator winding resistance between phase terminals at 200 C: 0.10–0.11 Ohm.
Adjustable voltage limits at a rotor speed of 3000 min-1 and a recoil current of 45 A, 12.5–14.5 V.
The height of the new brushes is 13 mm.
The minimum height of the brushes protruding from the brush holder is 8 mm.
Engines are equipped with starters (pic. 16.3) power from 1.4 kW to 2.2 kW, depending on the engine model, which provide the initial spin-up of the engine crankshaft to a frequency of 300 - 350 min-1, which allows the engine to be started.
The Bosch DW starter has a planetary reduction gear. The armature shaft rotates in self-lubricating bushings. The starter flange is bolted to the power unit. Checking the functioning of the traction relay must be carried out in the following order. Prepare auxiliary wires and remove the starter from the power unit.
Apply to terminal «50» +12 V voltage from the battery, using the auxiliary wire. Bypass, auxiliary wire terminals «50» And «30» starter, the drive gear should move sharply forward.
If the traction relay does not work, then remove it and replace it with a new one.
