Synchronous sources operate according to the equation:
(Hz) = (Poles)*(RPM)/120.
Generation can occur at any frequency that meets this
condition. Every electrical distribution network has its
preferred freqeuncy; North America is predominantly 60 Hz,
while Europe and Asia tend to favor 50 Hz. However, several
other frequencies also exist - ranging from 25 Hz to
several megahertz.
