[...] if you expect them to last,and it would seem prudent to limit the torque input to below 70,corresponding to about 1.7 HP.(at 130 input rpm)
crossbreak wrote:Has anyone ever seen a gearless friction drive planetary except the NuVinci? Opened up a so called "geared" sensorless hubmotor a Q126-SWX, reated at 36V, 210 rpm and 6.1amps
The ratio is about 1:10 I guess
I'd like to see how this performs at 72V
I ask myself if a KU123 100V caps can handle 72V??
I think this gearless hub motor will slip and not do very much at high power. They also have been known to crack the outer ring. If you want power, it has to be gears, not friction type.

You have done a lot of different things in a short time! Very cool!
