Subject: | 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.
Thanks,

Hi Guys
I'm thinking of using this 'engine start' button (only the button, from the p
anel shown) on the RV9 - it looks more than a simple 'push to close' wiring,
am I still good to go with this item
Best regards
John

The LS-1A and LR3 regulators are for alternators with a field winding. If the
Briggs & Stratton alternator is a permanent magnet type (dynamo), then a permanent
magnet type regulator must be used.

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.

It is not a matter of a regulator handling the alternator output, but rather the
ability of a regulator to handle the aircraft load.

John,
I've been using one of these for the last 3 years, with the illuminated
bit used as a starter warning light.

Although I think I got it cheaper from somewhere else. The one you chose
looked a bit complex.

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?
Bob . . .

It appears that this kit comes with a relay
for boosting the current handling ability
of the rather Lilliputian switch. 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.

Sorry not to make that clear - this switch is used to engage a regular
starter relay.
