Turn a car alternator into alternative energy by building this cheap and easy homemade wind generator. If you can turn a wrench and operate an electric drill, you can build this simple generator in two days. You can use any vehicle alternator with a built-in voltage regulator.
Can I use an alternator to generate electricity?
Yes, alternators generate electricity most efficiently when driven by an internal combustion engine. Their application in a motor vehicle is common. Also as a stationary power source to charge batteries for off the grid power.
Would a wind turbine work on a car?
Wind turbines can be put on cars but the energy generated by the air rushing by would actually have to be generated by the engine by burning fuel. Every watt from the turbine would require 10 watts from the engine, or -9W.
Why do cars use alternators instead of generators?
Alternators have several advantages over direct-current generators (dynamos). Alternators are: Lighter, cheaper, and more rugged.The brushes in an alternator carry only DC excitation current, which is a small fraction of the current carried by the brushes of a DC generator, which carry the generator’s entire output.
How much power does 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.
Can a car 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 run an alternator with an electric motor?
You can use a DC motor to drive an alternator in order to invert a DC energy supply into AC. But you would be setting up a system with needless mechanical complexity. It would not be economical to needlessly drive an alternator by an electric motor. Magnetic force in an alternator causes a mechanical resistance.
How fast does a car alternator need to spin to produce power?
Most alternators need to spin at about 2,400 rpm at idle, have their maximum output above 6,000 rpm, and should never exceed 18,000 rpm.
How can I generate electricity at home for free?
Generating Electricity at Home
- Residential Solar Panels. Every ray of sunshine that lands on your roof is free electricity for the taking.
- Wind Turbines.
- Solar and Wind Hybrid Systems.
- Microhydropower Systems.
- Solar Water Heaters.
- Geothermal Heat Pumps.
Can a car alternator produce 110 volts?
An alternator converts the mechanical energy provided by a vehicle’s engine into electrical energy.Thus the 12-14V DC output produced by your alternator can be converted into 110V AC current.
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.
What can a small wind turbine power?
The smaller or “micro” (20- to 500-Watt) turbines are used in applications such as charging batteries for recreational vehicles and sailboats. One- to 10-kW turbines can be used in applications such as pumping water. Wind energy has been used for centuries to pump water and grind grain.
Can a wind turbine charge a battery?
As stated previously, wind turbines are generally used to charge battery banks or feed an electrical grid. Both of these applications required dump loads but let’s examine the battery bank application in more detail. A wind turbine will continue to charge a battery a bank until the battery bank is fully charged.
How can you make a wind-powered car?
Procedure
- Poke the upright skewer through both ends of your smallest sail to hold it in place.
- Place your fan on the floor at one end of a long hallway or large room.
- Place your car in front of the fan, and turn the fan on.
- Replace the smallest sail with your next-biggest sail, and try again.
- Try with your largest sail.
Does an alternator produce AC or DC power?
Car batteries operate on one-way direct current (DC) electricity, while alternators output alternating current (AC) electricity, which occasionally flows in reverse.
Which is better generator or alternator?
Generators are considered less efficient. Alternators have a higher output than generators. Generators have a lower output when compared with an alternator. Alternators use only the required amount of energy and thus, it conserves more energy.
Can you replace a generator with an alternator?
Conversion from a generator to an alternator is a task that requires the vehicle to change from positive to negative ground as an alternator will never work on a positive ground state. Switch off the engine of your vehicle and disconnect the clips of both the negative and positive terminals of the car battery.
How much HP does an alternator draw?
An alternator takes about 1 HP for every 25 Amps of power. At full output, a 100 Amp alternator will need about 4 HP.
How many watts can a 120 amp alternator handle?
thats an average between output surges. Thats just sort of a relative rule of thumb. The other sorta relative rule of thumb is that 10 amps can translate to somewhere in the neighborhood of 100 watts… so a 120 amp alternator could do 1200 watts.
Do alternators charge at idle?
Yes, the alternator does charge the battery while the car is idling – regardless of the load on the battery. However, if your electrical use load (radio, lights, fan, etc) exceeds the amount of charge the battery is receiving from the alternator, you will end up with a discharged battery at some point.
Can DC motor generate electricity?
Originally Answered: Can we use a DC motor for generating electricity? A DC Motor can be used as a generator. You will need a prime mover such as a turbine or an IC engine or even hand cranking to rotate its shaft. based on its design (RPM vs voltage), it will generate DC output voltage.
