How to manage Volts and amps off of a DC Generator?
August 30th, 2010 | 
Author: (This isn’t my plan, this is just and EXAMPLE)
If I hook up a either homemade electric generator or car alternator (should be same thing, correct me if I am wrong) to a bicycle tire, how would i manage the amount of Amps/Volts coming from the generator?
If you need more info Email me @ brodieraces2@yahoo.com Thanks in advance Brodie
Brodie, alternators are constant voltage generators. Yes they make them for bycicles too! It always puzzles me why they call them alternators when they are not; they are direct current generators. That’s why they charge you D.C. battery. Alternators are alternating current generators in which I deal with in my jobs!
Example: How do you suppose wind generators generator the proper voltage?

Can I use a 17.5 HP engine for a generator?
Can I use a 17.5 HP engine for a homemade generator? Is that too much HP and somewhat pointless or will the generator be able to produce more power?
Thanks!
What alternator do I need?
After factoring in losses and so on, a good figure to use is 500 watts per horsepower. Your 17.5HP engine should be able to supply 8750 watts continuously. Depending on the alternator the surge rating could be much higher. The engine will need to operate at a constant speed. If it is directly connected, for the AC output to be 60Hz it must be either 1800RPM or 3600RPM, depending on the type of alternator. A belt or gear type drive would have to factor in pulley sizes as well.

Homemade generator, power questions….?
Ok, so I’ve built myself a homemade gas generator, right now it runs great, producing between 12 and 14 volts DC when idling without load.
It uses a 55 AMP car alternator which produces DC current. Based on an 55 amp alternator producing 12V DC what would be the largest inverter I could hope to run for 120 AC? I know a 400 watt inverter would be fine, but would a 600 watt one work to?
The generator voltage is designed to charge a car battery, so it is actually something like 14V on a car alternator when running at proper speed. Check that the inverter is happy with slightly over 14V. I expect it would be. Also it is DC with a significant ripple voltage unless a battery is in between, so some inverters may not like that. The generator itself may not operate properly without a battery either. One result could be larger than expected DC spikes, which could harm the inverter.
The maximum power at 14V x 55A = 770W. We can assume that the 600W inverter will run right up to close to its maximum power. There is nothing to stop you using a larger inverter. Car alternators are limited in current by design. The inverter draws a current that depends on the load connected. It will not be suitable for loads above 600W. I recommend you use it with a small car battery, and then the inverter can run briefly at higher currents, such as when a fridge motor is starting, and the conditions for the generator and the inverter are as they were intended. It might be possible to use a large capacitor or bank of them (approaching 1 Farad) of 25V rating instead of a battery.
The final story depends on the inverter itself. Incidentally, a true sine wave inverter is the best way to go, if yoiu want to run fridges and electronic appliances including fluorescent lamps..
