Can you make a generator out of an alternator?

Can you make a generator out of an alternator?

Another method of running your house off of a homemade generator setup involves a bank of batteries, power inverter(s), and using automotive alternators in a small backyard windmill or other power source like a lawn mower engine to turn the alternator. Here is an example of a windmill using an automotive alternator.

Can an alternator be used as a motor?

The humble automotive alternator hides an interesting secret. Known as the part that converts power from internal combustion into the electricity needed to run everything else, they can also themselves be used as an electric motor.

Can you build your own electricity generator?

Can you build your own generator? Yes, you can. This article outlines how to make a small scale electric generator, but there are many tutorials online for DIY generators. Search online to find instructions for the type and size you’re planning on making.

How many watts can a car alternator produce?

Conventional alternator may only produce power for about 500 Watt to 600 Watt. But nowadays, a single alternator can produce power up to 2500 Watt, depending on the power demand. The power that can be produced by an alternator is determined by the alternator rating.

How much power is needed to turn an alternator?

An alternator takes about 1 HP for every 25 Amps of power. At full output, a 100 Amp alternator will need about 4 HP. For a long time, most alternators don’t operate at full output.

What is the minimum RPM of a 12v car alternator?

Typically, the lowest speed at which a car alternator is able to generate 12VDC is about 1,800 RPM.

Can an alternator produce 240 volts?

Therefore, you need an alternator that will produce at least 125 Amps. In reality, you need more than that, in order to still have 1500W after you get done converting it to 240V. Fortunately, without trying too hard, I could find 200A, 250A, and 300A (2400W~3600W) alternators … so this is definitely possible.

How many watts will a car alternator produce?

Is there an alternator for an AC generator?

Shown here at the left is a prototype of a project I’m experimenting with for my own use. The AC generator head is direct coupled to the Tecumseh 8 HP motor, and has a belt driven 12 volt alternator mounted to our Horizontal generator bracket which is attached to the motor.

How much power do I need for an alternator?

Of course running an alternator exclusively on this engine is an example of overkill but the combination of the lower output of AC at the same time as DC is available makes for a fairly efficient use of fuel and resources. In my application, I don’t require more than 2500 watts of AC power which would normally require about a 5 HP engine.

How much power does a 12 volt generator have?

So, if you are using an 8 HP motor with this AC generator head and can insure you never will use more than say 2500W of AC power, then there is enough horse power left to be able to belt drive a 12 volt alternator running at say 40 amps (14.4 volts x 40 amps = 576 Watts) with some head room when belt driven off the same shaft.

What kind of alternator do I need to run house lights?

But if you’re living off the grid and doing so on a budget consider that you can run your house lighting system on a 12v circuit with battery backup simply by using automotive alternators and batteries (actually deep cycle marine batteries work better) with 12v lights.
