    Generator
In summary: Alternators can be purchased withoutputs but it is not necessary for your project.In summary, you would need a powerful magnet and a small DC motor to make a generator that can produce electricity.

hey i want to create a simple working generator that can be used to produce electricity so that i can operate a small fan and a bulb. power produced should preferably be ac in nature but dc can also be made to work.

i just wanted to know how much powerful and what size of a magnet is required to fulfill the criteria ? and also the rpm of the generator needed be produced .
can anybody help..?

Welcome to the PF.

What research and reading have you done on your own so far?

What source of energy were you planning to use to operate it? Hand crank? Wind? Water? Hamster wheel (my favourite)?

i just wanted to know these facts so that i can get my head straight and i have ample data before i really dive into this project...

Nowadays, the magnets you can buy cheaply are really impressive. It will be easy to produce a strong enough field if you can make yourself a reasonable 'yoke' to rotate your coil in. Have you found information about the basic design of a generator? If you do not specifically need DC (and your applications don't) then and alternator (AC) is the easiest to make.
We like to help but I don't think anyone here will provide you with an actual design so, as berkeman has asked, what do you know so far? Which sources have you used? Spoon feeding is not in our nature - it's not good for you. :smile:

Perhaps just try using a small DC motor as a generator first.

You could study the design of automotive alternators. A typical alternator produces 3 or 4 phase AC which is converted to DC internal to the unit. Typical DC outputs are 100 - 150 amperes at 13 - 15 volts
 

What materials are needed to build a home-made generator?

To build a home-made generator, you will need a DC motor, a battery, a rotor, a stator, wires, and a housing to hold all the components together. You may also need tools like pliers, wire cutters, and a soldering iron.

How does a home-made generator work?

A home-made generator works by converting mechanical energy into electrical energy. The DC motor turns the rotor, which is connected to the stator, a stationary component with wire coils. As the rotor spins, it creates a magnetic field that induces a current in the wire coils of the stator, producing electricity.

What can a home-made generator power?

A home-made generator can power small electronic devices such as phones, laptops, and LED lights. Depending on the size and power of the generator, it may also be able to power larger appliances like refrigerators, microwaves, and power tools.

Are there any safety precautions to consider when building a home-made generator?

Yes, it is important to take safety precautions when building a home-made generator. Make sure to disconnect the battery and wear protective gear when handling electrical components. It is also crucial to follow proper wiring techniques to prevent electrical hazards.

Can I use renewable energy sources to power my home-made generator?

Yes, you can use renewable energy sources like solar panels or wind turbines to power your home-made generator. This can make your generator more sustainable and environmentally friendly. However, you may need additional components and wiring to connect the renewable energy source to your generator.
