Alternador

Key Components:

• Stator/Rotor: 3-phase windings producing AC current

• Diode Rectifier: Converts AC to DC (600W+ capacity)

• Voltage Regulator: Maintains 13.8-14.4V output

Critical Functions:

• Battery Charging: Compensates for discharge cycles

• System Power: Supplies all electrical loads during operation

• Load Management: Adjusts output to demand

Technical Specifications:

• Efficiency: 55-75% (improved in modern designs)

• RPM Range: 1,500-15,000 (2-3x engine speed)

• Bearing Life: 100,000+ mile design standard

Common failure symptoms:

• Dimming lights (undercharged condition)

• Whining bearings (wear indicator)

• Battery warning light activation

Modern advancements include:

• Smart regenerative systems

• Integrated starter-generators (ISG)

• Lightweight high-output designs

This vital component typically lasts 7-10 years while powering increasingly complex vehicle electrical systems.
