How much copper is in a car generator?

At about five pounds.

Car generators.

It is the main power source of the car, and its function is to supply power to all electrical equipment (except the starter) when the engine is running normally, and charge the battery at the same time.

On the basis of the three-phase stator winding of the ordinary alternator, the number of winding turns is increased and the terminal is drawn out, and a set of three-phase bridge rectifier is added. At low speeds, it is output in series by the original winding and additional winding, and at higher speeds, it is only output by the original three-phase winding.

The things you need to pay attention to when buying a car are as follows:

1. Confirm the purchasing ability

Determine the purchasing ability, after buying a car does not affect the overall quality of life of the family, generally based on the average income of the family in the past three years, generally take out 20% of the family for three years, but not more than the fixed assets of the family.

10% of the value.

2. Concerns:

The most important thing for a family car is safety, followed by affordability, because the safety of the car carries the life of a family, so safety is the top priority.

3. On-site confirmation:

According to the above two steps, basically determine the several models to buy, and go to the 4S store in person.

On-site confirmation, including test drives, inquiries, loans, repairs and maintenance, etc.

Have you ever dismantled it? Fooling around here. I have dismantled dozens of scrapped car generators, removed the windings, rotors and the copper sleeve of the rotor head and weighed them, about one catty and six taels to nearly two catties, and various manufacturers may be a little different.

Hello! The inside of the automobile generator is made of copper material with rotor and stator coils, the two coils are copper wires coated with insulating paint, and the total weight is only a few taels when they are removed.

I don't know if it will help you.

Engines generally do not contain copper, mostly iron, or aluminum.

It's not much, it's less than 1 catty, and some of it is aluminum.

When the power factor is 1, the 300 kilowatt hall section generator, the full load output of the power is 300,000 kWh per hour, from the technical parameters of a brand of generator can be inferred, if there is a radiator, the copper quality is about 600kg; If it is equipped with a heat exchanger, the copper mass is about 500kg. The loss of generators can be roughly divided into five categories, namely, stator copper loss, iron loss, excitation belt and volt pin magnetic loss, electrical additional loss, and mechanical loss. In the operation of the generator, almost all losses are expressed in the form of heat generation.

1) The copper loss of the stator is the loss caused by the stator current flowing through the stator winding. 2) Iron loss refers to the loss of generator flux in the iron core, mainly the hysteresis loss and eddy current loss generated by the main magnetic flux in the stator core, and also includes additional losses. (3) The excitation loss is the loss generated by the rotor circuit, which is mainly the copper loss caused by the excitation current in the excitation circuit.
