Alternator needs battery power to generate power?

[Yendor]

Thanx mate..but..

Alternator stator winding need the field winding(magnet) to generate electricity out of the stator winding.
Then without a battery to initially turn the field winding into a magnet it apparently won't work?
But, once the stator winding started generating electricity, it can feedback to the field winding and feed each other?

So, it it essential to have a battery connected to the field winding, at least for a fraction of a second to generate electricity out of the stator winding?

Does it work in theory?! I mean like chicken or the egg first sort of situation(which obviously I don't have to understand, but would love to ).
Is possible by wiring up an alternator to self excite by connecting the trigger wire to B+?!!
If I understood you correctly above, it's possible, provided I work out the proper RPM spot for that by experimenting?

Are you talking without a battery fitted?. Without a battery fitted I would doubt an alternator will start charging.

I understand that without a battery, alternator B+ output voltage won't be smooth(battery function as a capacitor to smooth the alternator's pulsed DC output?).
So, if I'm to use an inverter, it would be a good idea to make alternator's output is smooth by connecting a battery to B+?!!
And that would also apply to many 12V appliances as well.

The only issue with using a decent size battery in the unit is that it would make it heavy. But, of course, the battery doesn't need
to be attached/fitted to the generator.

Without a battery fitted the regulator will have a hard time controlling the voltage. Depending on the load of accessories voltage could rise up to 19 volts
