DaimlerChrysler clutch switch.(DaimlerChrysler Corporation)STARTER MOTORSStarter Motor PurposeThe starter motor converts the electrical energyfrom the battery into mechanical energy forcranking the engine. The starter is an electricmotor designed to operate under great electricalloads and to produce very high horsepower. Thestarter consists of housing, field coils, an armature,a commutator and brushes, end frames, anda solenoid-operated shift mechanism.Figure 9-21. When the automatic transmission is inPARK or NEUTRAL, a transmission lever touches thecontact and completes the control circuit to ground.(DaimlerChrysler Corporation)FRAME AND FIELDASSEMBLYThe frame, or housing, of a starter motor(Figure 9-24) encloses all of the moving motorparts. It supports the parts and protects themfrom dirt, oil, and other contamination. The partof the frame that encloses the pole shoes andfield windings is made of iron to provide a pathfor magnetic flux lines (Figure 9-25). To reduceweight, other parts of the frame may be made ofcast aluminum.
