• 600-825-6370 600-825-6310 RKD60A02 Alternator KOMATSU Excavator Engine Parts For SA6D1408E

• Specifiion

• Function

1.Power Generation: When the engine runs, the alternator’s rotor (driven by the crankshaft belt) spins within a stator coil, generating alternating current (AC) via electromagnetic induction. This AC is converted to direct current (DC) by a built-in rectifier, supplying 24V power to the excavator’s electrical systems (e.g., lights, sensors, display panels).

2.Battery Charging: Excess electrical power is directed to the battery, maintaining its charge (typically 24V) to ensure reliable engine starting and backup power for systems when the engine is off.

3.Voltage Regulation: The internal regulator stabilizes output voltage at 27–28V, preventing overcharging that could damage the battery or electrical components.
