If a car alternator (rotor) runs at 1500 rpm, how much watt will it produce? Does any one know? I don't need exact value.

Maybe I have enough information..... [smirking]
Car alternators usually come in 65Amp and 85 Amp rating.
These values refer to a rotor speed of 4000 and 5500rpm respectively.
We assume that the regulator keeps the voltage somewhat stable at 13Volt (mean value).
There is an output graph of Amp versus rpm. and it shows
that at only 1500rpm, the -
- 65Amp type produces approx. 10 Amp ( x 13V ) = 130 Watt
- 85Amp type produces next to nothing.
So it is important what size your crankshaft pulley is, because that determines your rpm.

Well you will have to give more information then just the rpm in order to get the Watts

heu u need to give more information to us to say the power generated by the car. becz the unit of power is watt hope u know.. and the formula for calculating the power is P=2* pi value(22/7) * N(speed)/ T(Torque) [ power= 2 multiply by pi value (i.e 22/7) multiply by speed(N) wohle divided by the torque (T)]..

It's a good thing you don't need an exact value because there are a few things you left out.

Are we supposed to guess the rest of the things.
