Also you can limit ERPM limits on the vesc to 60k/-60k. Make sure you do not check the box that says limit ERPM with torque. I’ve heard it applies the brakes at full speed.
Well, im using 12S… So thats why I asked, but the torque should be fine because I have a gear ratio of 2.6, which means the motor gotta turn 2 rounds to turn the wheel 1 time?
I only see “Limit ERPM with negative torque”, so I gotta uncheck that one and limit the Max ERPM to 60 000?
Since I have a 300KV motor with a 12S setup, it means it will draw much more amp, and the battery will drain faster?
If I had a 100KV with a 12S setup would that mean it would draw less amps?
Limit ERPM with negative torque is the box you need to uncheck.
There is no advantage to using a 300kv motor with the erpm limited to 60k
Since the 300kv motor has less torque, you might draw higher amps and you may experience problems with the motor overheating.
You would be better of to see if Alien will let you return that motor for credit on a 170kv motor.
Thanks, but overheating is not a problem. It will be sealed with oil.
Hmm, if I had the 170KV motor, it would be around 47kph, on 44.4V, thats why I bought the 300kv, because of much more speed… so I would always be able to limit it to 50kph so I wouldnt feel powerloss when the battery is at 3.3, because it would still be able to drive in 50kph.
But if I had the 170KV motor I could change the middle gear to a 30 teeth instead of 25 teeth, and the other to 10 teeth.
With the right wheel size and gearing at 12S should be very doable
You could use a 190kv motor, assuming most are actually lower kv you’ll be at the limit with 12S
@scepterr
btw, shouldnt my gear reduction fix this issue with the 300kv motor?
My gear ratio is 2.6
“While in many applications gear reduction reduces speed and increases torque”
The wheel is 90mm.
Cool, but you have the opposite of gear reduction which gives you more speed and less torque, mine gives me less speed and more torque. Well if the torque is that bad, I will return it.
