- Key functions & working principle
| Working Principle | 1. The engine’s crankshaft drives the alternator pulley via a serpentine belt, rotating the alternator’s rotor (armature) inside the stator (stationary windings) |
| 2. The rotor’s electromagnet (powered by the battery) creates a rotating magnetic field that cuts through the stator windings |
| 3. This induces an alternating current (AC) in the stator windings |
| 4. The integrated rectifier converts AC to direct current (DC) |
| 5. The voltage regulator controls the rotor’s magnetic field strength to maintain a stable 24V DC output, charging the battery and powering the machine’s electrical systems |
| 6. When electrical demand is low (e.g., idle), excess power charges the battery; when demand is high, the alternator supplies power directly |
| Core Functions | 1. Battery Charging: Maintains the 24V battery at full charge, ensuring reliable engine starts and power for auxiliary systems (e.g., cab lights, control panels) |
| 2. Electrical Power Supply: Powers all DC electrical systems during machine operation (hydraulic control valves, safety sensors, air conditioning) |
| 3. Voltage Stabilization: Prevents voltage spikes/drops that could damage sensitive electronics (e.g., engine ECU, monitor displays) |
| 4. Overload Protection: The voltage regulator limits output to avoid damage from short circuits or excessive electrical load |
