I just got back inside from lots of testing. I ended up putting the fan inside the motor and running it off of one 6s lipo. It was pretty loud and it didn't burn up! The exciting thing is that I had LOTS of trouble trying to get the motor up to the 95*C buzzer. I blasted though town at 35+mph, went up a mega hill maintaining 32mph, and only near the end of my ride did the buzzer go off.
I improved my top speed! With the 3-speed switch settings, I set one to 120%. I was able to go from about 38mph to 41mph on a smooth flat road.
I also beat my speed record; Now it's 46.9! I was going down my mega hill..
I played with the block settings for awhile and I really didn't feel a difference. It's at 10 right now, but I think I'll change it back down to 4 or 5 because that is what I've seen other people using.
I tried to get more power constantly, and I ended up with only 31.51a and 2133w. The bike felt faster then before but it wasn't anything amazing. I did this by raising the max current from 40a to 57a. Both the phase current and rated current are maxed out. If anyone is running a 9c and making over 2500w, please let me know what settings you are running
. A screenshot would be great. This is what I have ATM
I took some more pictures too
Here is how I have my fan. It's a 12v fan overvolted to about 24v.
I couldn't fit the wires through the axle, so I dremeled a small slot in the axle and made the wires come out crystalyte style.
Here's a shot of the other side of the motor. JRH, please explain to me what you mean,, Should I attach cooling fins to my motor?
And I'm open for compliments on my clean wiring!
One problem I may have is a little rear axle play. When I hit the regen I can feel the axle shift. Maybe I should try to shim my torque arms a little more?
