Where can i buy high output alternator?

Question

I just want to know if there any alternator that can produce 120Vac within 3600rpm.

Thank you.

Answer 1

Yes, 99.9% of the alternators used in portable generators will produce 120 Volts AC at 3600 rpm. These are single pole set generators, thus the need for the high speed.

That said, if you are after an automotive generator that will produce 120 Volts AC at 3600 rpm, now you have a much different problem. Common automotive, or truck alternators operate at a much higher frequency. While there are, I guess, specialty shops that have them, or can make one for you, it is going to be expensive. A much more cost effective approach is to use an inverter.
