I was posting in another thread and It made me think of an Uneven drive board I built recently. the build was a total accident, I was making a DR for a friend with parts he provided and he accidentally bought 2 motors of different size. so I have by total accident probably pioneered the dual uneven drive board. I figure no one else has probably been stupid enough to try this, but I was actually really interested to see how it turned out. so I had one motor which was around 200kv and one with about 400kv would it work? would it explode?
Or, would it work like some sort of sequential twin turbo system where the torque from the 200kv would assist getting the board off the line and up to the top where the 400kv would take over and boost the top speed?
well turns out it was the twin turbo option. who knew? seriously, the low down is taken care of by the extra torque of the 200 and the 400 kicks in and boosts acceleration and top speed!
each motor is powered from its own individual ESC so the loads on each motor are different but shared slightly, handled by different electronics so there is no real feedback or connection from one motor to the other. So what happens when the 200kv motor exceeds its theoretical RPM limit?
think of it this way: whats your theoretical top speed? mine is about 35km/h but we have bombed hills right? i have had my board up to ~38km/h-40km/h which is already exceeding the max RPM of my motor. So you could say its just the same as going down a hill, the load on the 200 will be reduced.
how long will it last? will things blow up?
Dunno. I’ll keep you posted.
