Hi,

Just a suggestion, the following page discusses phase rotation in 3-phase circuits.

http://www.allaboutcircuits.com/vol_2/chpt_10/3.html

However, the winding arrangements do no correspond to the arrangement in an alternator (or to the discussion). The clockwise sequence should read 1a-3b-2a-1b-3a-2b to produce a phase sequence of 1-2-3, with subsequent phases 120 degrees apart.

It might just be an abstract image, but it would be better to have it accurate and clear.

Thank you.
