How much copper is in an alternator

This is an important figure due to the fact that OEM alternators are typically ill-equipped to handle additional loads from aftermarket equipment and upgrades. When that happens, and your alternator output is unable to fully meet the needs of your electrical systemyou can experience anything from dim headlights to severe drivability problems.

Alternator, how it works, symptoms, testing, problems, replacement

Left alone, this problem will eventually lead to the alternator burning out altogether. While the output rating of an alternator gives you an idea of what it's designed to put out, the only way to see what an alternator is actually capable of is to test it. To that end, you can measure the actual output of an alternator under a simulated load, which allows you to get an idea of what it is capable of putting out in real-world conditions.

The first is the alternator output rating, which is the amount of current that a unit is capable of producing at a specific rotational speed.

The other thing that alternator output can refer to is the amount of current that a unit actually produces at any given time, which is a function of the physical capabilities of the alternator, the rotational speed of the input shaft, and the momentary demands of the electrical system.

In this case, this alternator is capable of putting out A 6, RPM. The last number is In essence, while maximum alternator output is dependent on the rotational speed of the input shaft, the actual output is load-dependent. That basically means that an alternator will never generate more current than is called for by the momentary demands of the electrical system.

What that means, in the real world, is that while an underpowered alternator can cause problems by not meeting the needs of your electrical system, a substantially overpowered alternator represents a lot of wasted potential.

In most cases, alternators are replaced due to normal wear and tear. Internal components simply wear out, so the best case of action is to replace it with a new or rebuilt unit that conforms to the same output ratings.

There are cases where it is more economical to rebuild an alternator instead of buying a new or rebuilt unit, but that is a different discussion. There are also cases where an alternator may burn out due to excessive demands over a prolonged period of time.

How much copper does a car alternator have in it?

This usually doesn't apply to vehicles that have factory car audio systems and no other additional equipment, but it can quickly come into play as you pile on more and more power-hungry equipment. In cases where an alternator seems to burn out faster than expected, and the vehicle has a powerful aftermarket amplifieror other similar equipment, then a replacement with a higher output rating may fix the problem.

All of this puts a serious strain on the charging system. We have previously discussed the battery and how that worksbut the other half of the charging system is the alternator. The alternator generates electricity by converting rotational mechanical energy into electrical energy.

This is the same type of device used in hydro-electric and steam-turbines power generators. The alternator consists of several components—stator armaturerotor rotating magnetic fieldand a bridge rectifier. Each has their own dedicated function. Inside the alternator, there are several main component assemblies. This shows the rotor and field wires. With the rotor removed, the stator windings are exposed. This is where the AC voltage is created. The stationary windings of the alternator are called the stator.

There are three coils mounted to the outer case of the alternator itself. Spaced degrees apart, each winding generates a current, creating a 3-phase power source. The rotor is an electro-mechanical component.

The mechanical rotation combined with the electrical field wires begin the process of generating electricity. This is the part of the alternator that spins.

This is where the alternator is controlled. The center of the rotor is an iron core, with a copper wire wrapped around it. When a current is applied to the wire, a magnetic field current is produced. The field current is DC, or Direct Current, the current flows in only one direction. The field has a North and South Pole, just like any magnet. Inside the case is the regulator and bridge rectifier. When these components go bad, you need to change the alternator immediately.

In order to control the output of the alternator, there is a regulator. This is the brain of the unit. As demand increases, the regulator increases voltage to the field wire, which in turn, produces a larger current output from the stator.

The regulator monitors the field current supply, the battery voltage, and the output. Most regulators are set Older vehicles mid 70s and older used external regulators.View our current updated scrap metal prices.

As a result, a lot of metal scrap is created that must be recycled. We buy as alternators themselves as their coppers cores. Scrap yards offer nice deals for alternators or starters, as they contain a copper core, which is a cable made of wound copper wire. Apart from that, they have more kinds of scrap metals, such as steel cases.

Alternators and starters are oftentimes bought at higher costs than electric motors due to the greater amount of copper obtained from them.

Just wondering if I'd make more money with the pile of copper vs. Last edited: Mar 30, The37KidMar 30, I just took some in, wasn't worth my effort to pull them apart. Just make sure to call a couple different places, rates had a decent variety here. Even between the same company but different locations. ProvienceMar 30, In South Carolina Deuce RoadsterMar 30, It only makes sense if you need more money for meth. Sorry to read that Randy, dirtbags are ruining everything these days.

Most scrap buyers around here have a special price for electric motors, More than Iron and less than copper. Starters and such are motors. Makes it not worth the time to take them apart. Last time i took in electric motors it was something like. Totally worth it if you are taking in old 50HP AHU motors, hardly worth the effort for a starter unless you have a barrel full of them.

What's New? Results 1 to 11 of Thread: Amount of copper wire in a generator. Thread Tools Show Printable Version. Amount of copper wire in a generator I need help coming up with a realistic amount of copper on hand for a story. I have a fictional company that makes propane powered generators that range from the size of lawnmowers to the size of cargo vans.

I have no idea how much power these could generate, but that doesn't matter. To make them, I assume they will have a lot of copper wire on hand. I found a place that sells foot spools of 22 guage copper wire for 40 dollars, which is just about what it's worth to recycle 3. The point I'm trying to make is that there is enough copper wire sitting around to justify the need for a compound style layout to the place.

To do that, I need some idea of how many of these copper wire spools they might go through in a week. To do that, I need some idea of how much wire is in a small generator. That's where the whole thing falls to the ground. I can't seem to find anything that tells me in a way I understand.

Mine are much smaller than that, but I don't know how to describe them accurately as far as output. I'm Not Evil. An evil person would do the things that pop into my head. To know how many spools they go through in a week you would need to know how many generators they made in a week, as well as how much copper is in each.

It's in the range 1 to 2 kg per kW for small generators. The design to get rid of heat makes larger ones more efficient but factors of safety also have to increase. Originally Posted by Ken G.

Join Date Jan Posts I have torn down many small motors for the copper. Above that I go about a pound per horsepower.Automobile alternators perform more duties than simply recharging a car's battery. A car's battery only provides enough power to operate the vehicle's starter when starting. Once the vehicle is running, pulleys on the running engine rotate a belt connected to the alternator, which then causes the internal coils of the device to generate power to replenish the battery for the next start and provide ongoing electricity to operate the vehicle's accessories and lights while in operation.

Since the s, alternators have been of the 3-wire type.

Inspect the back and sides of the alternator to locate the two wire connectors. One of the connectors is typically a threaded bolt protruding from the back the opposite end from the pulley that a wire with a boot on the connecting end is snapped onto.

Look for a separate wire with a wire terminal on the end. It is the only other separate wire without a "boot" on the end of it, but rather a round slide-on terminal that slides over a bolt connected to the vehicle's frame. This connection is "Ground" and completes the negative - voltage side of the electrical circuit. The terminal is slid over the threaded post of a bolt and then secured by tightening a nut onto the terminal.

Identify the third wire, which is typically two wires with a snap-in plastic connector on the alternator end. This connector is manufactured so it may be inserted into the connector socket on the alternator one way only. If the voltage rises above or falls below 12 Volts, the alternator's internal voltage increases or reduces power output to maintain 12 Volts to the battery and the systems of the vehicle during operation.

Step 2 Look for a separate wire with a wire terminal on the end. Tips Always mark each wire that you remove from an old alternator, if necessary, to ensure you can easily replace the wires in the correct connectors when you install the replacement alternator.

Vehicles older than a model may require all of the connections of the alternator, except ground, to be connected to positive and negative terminals of an external voltage regulator instead of directly to battery and ignition connectors.
