Re: [A/S] Generator?

[Dick Kenan <as5368@xxxxxxxxxxxxxx>]

         Physically and electrically, I think they are the same thing.  The 
difference in principle is that an automotive "generator" has a mechanical 
rectifier built into it via split commutators/brush system.  "Alternators" 
(in automobiles) have slip-rings (continuous rings, not split) commutators 
and solid-state rectifiers (diodes) built into their frames.  Both output 
pulsating DC voltage.  "Generators" in electrical plants, on the other 
hand, produce alternating current.
         Mechanically, they are, of course, quite different, over and above 
the kind of rectifiers they use - the solid-state rectifiers allow the 
mechanical designer to accommodate other concerns.  To me, they alternators 
look like they have a larger radius.  I believe you're correct that an 
alternator can not work as a DC motor; so, it cannot be used as a starter, 
as you said.
