MOTOROLA ALTERNATOR
1. Slip rings. 2. Fan. 3. Stator assembly. 4. Rotor assembly. 5. Brush and holder assembly.Alternator (Nippondenso)
The Nippondenso alternator has three-phase, full-wave rectified output. It is brushless. The rotor and bearings are the only moving parts. There is a 9G4574 Alternator with 35 amp output.
NIPPONDENSO ALTERNATOR
1. Fan. 2. Front frame assembly. 3. Stator assembly. 4. Rotor assembly. 5. Field winding (coil assembly). 6. Regulator assembly. 7. Condenser (suppression capacitor). 8. Rectifier assembly. 9. Rear frame assembly.When the engine is started and the rotor turns inside the stator windings, three-phase alternating current (AC) and/or rapidly rising voltage is generated.A small amount of alternating current (AC) is changed (rectified) to pulsating direct current (DC) by the exciter diodes on the rectifier assembly. Output current from these diodes adds to the initial current which flows through the rotor field windings from residual magnetism. This will make the rotor a stronger magnet and cause the alternator to become activated automatically. As rotor speed, current and voltages increase, the rotor field current increases enough until the alternator becomes fully activated.The main battery charging current is charged (rectified) from AC to DC by the other positive and negative diodes in the rectifier and pack (main output diodes) which operate in a full wave linkage rectifier circuit.Alternator output is controlled by a regulator, which is inside the alternator rear frame.Alternator Regulator (Bosch)
The voltage regulator is an electronic switch. It feels the voltage in the system and gives the necessary field current (current to the field windings of the alternator) for the alternator to make the needed voltage. The voltage regulator controls the field current to the alternator by switching
