[AT] Generator vs. Alternator

[Robert L. Holtzer]

More output at lower engine RPM is a major benefit.  Also the use of 
constant brush contact instead of segmented armature contact lengthens 
brush life substantially.  Possibly the winding of the armature is less 
costly for an alternator than generator?  Will be interested in more 
knowledgeable comments!
