How To Build A Bicycle Generator
Please, before trying to build this, be sure your motor uses permanent magnets; otherwise it will not generate electricity.Few motors, these days, use magnets. I'm very surprised no one talked about that.
Probably not, as a stepper motor has wierd wiring (not -ve and +ve)
How much would the materials cost? Thank You!
HelloI have gotten all the parts ready to build this the only problem is that I cant get the motor to spin as the connection is too lose. How did you manage to get it to rotate like that? This is the v belt and motor I used. Many thanks.
I was actually hoping this would have been, or included instructions, on how to make the bike produce power while you're outside doing stuff, not just a stand still bike. I want to be mobile while I power a battery on the bike. My goal was to replace the back tire with a motored tire, and charge the battery that powers this motor while I ride, and turn the motor on when I need to go up a big hill or need a break in peddling for a bit.
What will the Independent, dependent and controlled/fixed variable be for this experiment?
I dont think distance actually matter but you can add a couple of gears in shaft which connects your dynamo with belt or add a shaft, use gear ratio gear 1 teeth/gear 2 teeth make sure first gear has more teeth than second one for more speed and effciency.
What is the point of the car battery? And What are those blue and red wires called?
Granted, while there are other factors that play into it (such as how MUCH electricity you can generate), yes you should be able to.
So I came up with a way to guesstimate the v-belt length you'll need to order for this project. It's pretty simple and should work with any sized bike. A quick note. You may want a bit more room for your generator, but mine is small enough that it fits nicely at the outer edges of the rim (see pic)Step 1: Measure the size of your bike's rear wheel. Mine (from rim to rim - not including the tire was 26" tall, which means I have a radius of 13". The equation to get the circumference of the rim is 2 x pie x radius = 2 x 3.14 x 13 = 81.64" around. Step 2: Subtract 1/4 of the circumference: 81.64 * 75% = 61.23Step 3: Add the diameter: 61.23 + 26 = 87.23" Long--------Optional Step 4: You can add extra length to the v belt in case you don't want the generator sitting just below the rear wheel's exterior. For instance to place the generator 1 foot behind the rear wheel, you add 12" for the extra distance behind the wheel, and then you use the Pythagorean theorem to get the additional v belt required to reach back to the tire: (12 x 12) + (13 x 13) ...then get the square root = 17.7". So to place the generator 1 ft behind the rear wheel of this bike, we add 29.7 inches to the 87.23" we already had and get 116.93"
am doing on this project...can i know ,how much distance to be kept between the cycle and dynamo in order to get max power? is this distance effect the power generation?can we add any extra equipment ,in order to look project differ from simple
Can i use fan's motor to generate elcricity???/
Can I use a stepper motor for this project? THANK YOU
