• Function

1.Generating Electricity: According to the principle of electromagnetic induction, when the alternator's rotor rotates, it generates a rotating magnetic field, and the stator coil cuts the magnetic field lines to produce alternating current. This process converts the mechanical energy from the engine into electrical energy, providing a power source for the entire machine's electrical system.

2.Powering Electrical Equipment: It supplies power to various electrical equipment on Caterpillar machinery, such as lights, ignition systems, control circuits, and hydraulic system solenoid valves, ensuring their normal operation. Whether it is the normal operation of the cab's air - conditioning, lighting, or the electrical control of the engine and hydraulic system, they all rely on the power provided by the alternator.
