The drive will work with a number of readily available RC motors.
The only "Perfect" RC motor for this that is currently available would be the Plettenberg. But at $1,100 who really wants to buy one (other than those of us who are insane and really impatient for the best)?
I wish this stuff was easier to adapt to bike use. But, we are close, very close. The ideal setup would be an Astro Flight twist throttle, running a Castle SHV200 ESC, into a motor like David is making, with a silent reduction drive.
My recumbent is close to my ideal. Heck, if I could pull 160 to 180 amps through my HV110, I would be happy as a pig in slop! The "Perfect" system can be setup right now. The problem is price. There are a couple $1,000+ ESCs that work for this, and a couple $1,000+ motors. But, the ideal setup should be available to the average Joe. I am thinking as long as you can setup a 4,000 watt drive for $1,000 (motor, ESC, and reduction), that is ideal.
Anyway, I am doing some programming on the drive unit today.
I highly doubt there will be much R&D needed with the reduction unit. I have already learned what I need to know with my recumbent. I am, essentially, using the same rough drive setup in a very compact, variable layout structure. But, all the components have proven themselves. I have 600 miles on my recumbent so far.
well i am insane and really impatient for the best
i think i will take the plunge with a pletty and an svh200 (are they out yet??) with one of your new boxes.
did you have the terminator? specs? i know you have posted all this info but i'll have to wade through to find it.
will the pletty drop straight into the new box? that would be cool then i could just work out what gearing i need and go with 25chain and sprockets?
i think you run at 48v on that which i could do, if i reconfig my pack from 66v 6.6ah to 48v 8.8ah that would be fine for me.
i think (dont flame me if im wrong) that my 123's will do 80amps for 1s and then another 80 for every paralell string ?
does that sound right?
Anyway i know they kick ass and certainly my pack wont let me down for supplying power.
If i folow Matts lead i would be running 48v (or whatever the 123 equivalant is) so i guess that would make my pack 4p allowing me to draw silly amps, being as the svh200 is 200 amps? i will be fine to supply anything i put on really
mmmmmm, pletty and svh200 could be the ticket, i have the patience to wait for Matts second box but i doubt i have the patience to wait for davids motor.
damn this ebike lark, i cant think about anything but drive systems night and day !!!!!
