Finally, let's examine how fast each alternator rotates in a
typical aircraft application.
In this case, the implication should be evident:
assuming all things equal, an alternator that rotates 8% slower
would last an equal percentage longer in an identical
application. But to further matters, as we've shown here,
all things are NOT equal: Plane-Power alternators are better
designed, better built and better performers in nearly every
engineering category than all other brands of aircraft
alternators.
So to sum it up...
