The role of the excavator generator is:

when the engine is running normally, it supplies power to all the electrical equipment except the starter, and charges the battery at the same time. The generator is the main power source of the excavator. excavator generator is composed of rotor, stator, rectifier and end cap, which can be divided into DC generator and AC generator. The working principle of an excavator generator is that when an external circuit energizes the field windings through a brush, it generates a magnetic field and magnetises the claw poles into the N and S poles. Notes for the use of excavator generator are: 1. Often clean the dirt and dust on the surface of the generator, keep it clean and well ventilated; 2. Regularly check the fastening of the fasteners related to the generator, and timely tighten the screws of each part; 3. When the generator fails to generate electricity, it should be eliminated in time.
