What's better, an alternator, dc motor, or another type of generator? |
I'm looking to make and store electricity using a bicycle generator. I have researched a few sites on how to build a bike generator but different people use different methods. Which of the above mentioned should I use to charge my storage batteries which in turn will power my lights and other small electrical items? Is one better than the other? Which is more efficient? Please email me if you have deep insite into making efficient bicycle generators. Thanks all for your help. An alternator is best value since they are cheap from a junk yard, are efficient and contain all the necessary electronics for regulation etc. the downside is that you may not be able to provide enough power for it to work. The human body is very limited at power production. Also bear in mind the alternator requires to be connected to a battery to work and many of them also need the indication lamp to be wired for them to work. A DC motor will give problems by overcharging at high speeds and tending to take power at low speeds as it contains no regulation circuits. This would be the alternator, more wattage for size can be had, a permanent magnet alternator does not require any external voltage source only a way to make it turn & it will produce electricity. http://groups.yahoo.com/group/weee-recyc... |
