6volt 3watt generator

Postby CharlaineC » Tue Jan 08, 2013 3:11 am



ok so i had a thought and might need to hook it up to test the voltage gain but I was wondering has anyone ever thought to use an old style bike alternator to help keep the battery charged. I'm talking the type that had the drive that ran on the top of the tier like this

I have one its a body ground positive wire to the battery type. its 6vdc @3watt I think that decent for a charging unit to work with the stator right? I was thinking that I could hook it up to the back of the bike to run when needed and then click out of the way when not. just like it was used on my bike. It would word to help during winter driving when the battery is struggling due to the cold.

I think it would be a lot easier and safer to just turn off 3 watts worth of lights.

Not in a million years. First off, those things are designed for bicycles going <15 mph, not motorcycles going >60 mph. You would burn it out and kill the bearings in short order. It would then seize, rub a hole through your sidewall, and cause a sudden blowout on your tire.

For 3 watts, not worth it.

This Idea came to me because I know unit worked really well on my Vespa and that runs like 25-30mpg I think. I know on the Vespa I wasn’t thinking for long term use, it was used only to keep the battery charged or to help run the lights. What I was thinking was using it strictly as a short term emergency charge assist type system. I was also not at all thinking of putting the gear head on the sidewall. I was thinking on the main meat of the tire, and it would be for example my battery is low because of the cold weather. Engage something like this and drive around town no more than 25 mph. for a few miles. Then disengage it, and I would never do it without a bench test. I was thinking of attaching it to a high speed drill and running it for an hr. to see if it would hold up to the stress.

If you only want to use it to help your battery in cold conditions or when it has been parked for a long time, I would recommend a battery charger!! Far more effective, looks better on the bike!! Also, your wing has a 12volt electric system not 6, the output of that generator is not regulated (but there is not enough power to do any damage) but it would take a while to mount it and wire it in, for no gain.. as stated the tail light on a wing is 5 watts, just remove one tail light and drive around with the standard alternator running, it would do as much good and is far less effort.. :D

PS shouldn't this be in the "just for fun" section!! :lol:

If you want a simple way to keep a battery charged up, look at a solar charger. I have one in my truck, as I've got so much electronic crap in there that it will run the battery down after a few days of not being run. If I'm not going to drive my truck for a few days, I just put the solar charger on the dash, and it keeps the battery topped up.

The solar charger is what I use now I was just thinking who's the generator and I wish to thank everyone for the great input

Assuming a 1/2" diameter wheel, and also assuming you run it off of the centre of the tire...

63,360 (inches per mile)/1.57 (gen wheel circumference)= 40,300 revs per mile.
A mile a minute at 60 mph, so....

Boom, I strongly suspect.

cheers.
