PMA and High RPM from a turbine...
Hey Forum,
I am working on a plan to build a recharging setup. What I want to do in theory is take a jet turbine or a smaller RC turbine that burns bio diesel and turns at around 60,000 RPM. I want to take this high speed rotation into a chain or belt system spinning 1-4 PMAs(Permanent Magnet Alternators). This generated electrical energy will then be stored in large super capacitors or 15 deep cycle batteries.
What I want to know, first is this possible? Also, I am thinking that really high currents will destroy the batteries, hence the use of the super capacitors. Can I still recharge the batteries from the Capacitors? I have found some PMAs that will put out 100 amps, but the website states that the horse power is unknown, so its just a reference. I don't know what the HP would be for a turbine, so I would just have to use an average number. I am thinking that there will be large amounts of heat, and the possibility of burning up the PMAs at that speed, so maybe throttling down the turbine, or using a reducing gear?
I want to calculate how long it would take to recharge the battery bank from this type of setup burning the bio diesel into the turbine. This is possible, but I need help assuming some values.
Lets figure: Battery - 225AH X 15 (# of batteries)
I could find very little on super capacitors and PMA specs.
Thanks,
