Subject: AeroElectric-List: Briggs & Stratton Stator Hi Bob, I=99m hoping you could offer your opinion on whether the LS-1A or the LR3 Controller could handle the output from two fixed stators ganged together in this fashion. The application is for the Solar T62-32T turbine power plant installed in the Helicycle chopper. The original design called for only one stator which limits the charging ability.

If the Briggs & Stratton alternator is a permanent magnet type (dynamo), then a permanent magnet type regulator must be used. http://www.bandc.biz/regulator14vhomebuilt.aspx You might consider using two regulators, one for each stator. The aircraft loads could be divided between the two, perhaps lighting on one and avionics on the other. The two regulators would have a common ground, but separate main buses. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=440323#440323 ________________________________ Message 4 _____________________________________ Time: 07:20:09 AM PST US Subject: AeroElectric-List: Re: Briggs & Stratton Stator From: "user9253" It is not a matter of a regulator handling the alternator output, but rather the ability of a regulator to handle the aircraft load.

The one you chose looked a bit complex. See also this .

The application is for the Solar T62-32T turbine power plant installed in the Helicycle chopper. The original design called for only one stator which limits the charging ability. As Joe correctly points out, the alternator controllers you cited are for automotive style, wound-field alternators either designed for or modified to run externally regulated. The stators you illustrated are interesting. I'm curious as to what the magnet-ring or rings look like to work with dual coils. It appears that the two stator's leads are brought out separately . . . and further . . . offset rotationally from each other. This offers an opportunity to rectify them separately (2-phase) and combine the outputs of the rectifiers for a much smoother DC power product (the RMS ripple on rectified DC from a 3-phase automotive machine is about 5% pk-pk. 2-phase would be larger . . . ~15% but still less than single- phase at 100%. This not-quite perfect DC would then need to be regulated with something more sophisticated than the legacy rectifier-regulators used with PM alternators. A switch-mode regulator would probably fill the bill. Have you seen any numbers on the charging rates in amps before and after for upgrading to two stators?

The same relay would be recommended for the switch that Peter has cited. Neither device would stand up robustly to switching loads imposed by intermittent duty starter contactors.
