 Posted: Wed Mar 18, 2015 6:50 pm Post subject: Questions on 912/914 alternators |
 |
|
Based on some testing accomplished today, I'm
initiating some proof of concept design work
on an after market rectifier regulator configuration
that may increase output power from the PM alternator
by 30-50% and, oh yeah, won't smoke like the legacy
Ducati part.
I'm seeing some conversations on the 'net concerning
an 'alternator stator upgrade or replacement program'.
Is anyone on the List familiar with what drove that
activity? I'm also in the market for a PM rotor and
a stator winding off a Rotax 912. If any knows of
an engine being parted out . . . or one that's presently
not airworthy awaiting overhaul, I'd be pleased to
'rent' the parts for a time.
These would be assembled into a bench-test alternator
without modification. They would be returned in an
unaltered condition after the tests are completed.

Can you provide a web link?
I assume that the power increase comes from increased efficiency of your new rectifier/regulator design, not from the PM dynamo. I would be interested in testing a prototype in my Rotax 912 powered RV-12 E-LSA. Although my rectifier/regulator has not failed . . . yet, many others have as reported on VansAirforce.

Yes, improvements in component capabilities
and performance . . . and market forces . . .
have encouraged us to look at R/R technologies
for the full line of PM power conditioners.
We have every expectation of offering a product
with greatly improved reliability. Improved
performance is a most welcome side benefit.
Rotax 912/914 is the largest PM system in
wide usage so I'm intently interested in
getting my hands on parts needed to craft
a test alternator that I can run on the
bench.
Once we have flightworthy POC devices,
we'll be looking for opportunities
to do field testing.
