Thanks for transfering the posts into here ! I felt guity posting in another
person's topic. waterbard I have to find the volts & amps I need to be
able to maintain 75mph/120kph climbing a long hill, say a 35deg slope.
I don't know what hp the 8" DC would be puting out doing that. That is
the worst power load I'd have to maintain from the pmm to the curtis.
Legaly I can only do 110kph down here in Aus. Launch max draw, is up
to the curtis model I buy isn't it ? waterbard I'm working backwards from
what volts & amps I need, to figure out what pmm revs I need, & what I
use to generate just over the minimum volts & amps I need. The pmm
I'm making is 16" dia x 13"lg + shafts sticking out each end to run 'gens'
I have to test what HP it takes to stop the pmm I'm making. Revs N/A.
I have a method of magnet field ramping. Aproach 35% & 65% Pushing.
New alignment is 172 mags pushing 100% at any one time = Torquey.
Possably the pmm with a gearbox, could push a car. But as you & I
know, it will act like an AC motor & start mild & increase with revs. I'd
rather power the curtis to supply a DC for early reving power !
If my pmm revs too high, even under load, I will make a shorter vers.
I can produce high volts & low amps, or mid volts & mid amps etc. If you
can see in your manual what volts & amps suits better temps, I'll aim
for those figures. Freeway at 110kph is 3200rpm. But up hill amp draw
at that speed, keeping with the traffic, is something I have to aim for.
I hope you can help me work backwards on this to work out my needs !
I will share the pmm method & gens etc if all goes well. Cheers !
