 Posted: Sun Sep 23, 2007 3:36 pm Post subject: External Alternator for 912S on Model 7? |
 |
|
Does anyone on the board have experience with the Rotax external alternator and the 912S/Model 7 combination? I'm nearing the completion of Kitfox 7 and will need more electrical power than is available with the internal alternator. I'm wondering if the alternator will fit under the cowl.
Thanks for the help,
Chris

The pad for the vacuum pump on the 912 series will also take an alternator. Does anyone know of a pad mounted alternator that will fit a 912S? I have done a google search but none specifically say they will fit the 912.

Yes the Rotax electrical power leaves something to improve upon.
Nobody wants the vac pump location because the rpms at that location are way to low = low amps.
Best bet is the belt driven unit which has an added pulley behind the prop. Some cowls will need a small bubble.
The Europa guys put an alt on the end of the crank, but the Kitfox engine truss and short clearances will defeat that concept.
I tried to design a stator pulley to avoid the bubble but could not find enough clearance for even the smallest alt.
The front belt might work with a John Deere PM alt without a bubble since the alt is so small. Seems like I remember that alt was around 20a? I suspect you will have to design your own brackets.
Do a Google search for a Canadian source version of the big buck Rotax auxiliary belt driven alt.

Check with B & C Specialties. They used to sell one that fit the 912ul.
