Try turning on traction control on if it isn’t. I know it’s one wheel but I had an issue with torque loss on the bench and traction control being off.
Also try messing with the throttle mapping curve. A positive exponential value will give you a boost at low throttle and smooth out at upper throttle. Shortening the postive ramping time may help as well.
Ive had prob in past running direct from comp. of course never on a beast like this. Hope u figure it out i wana see this thing attempt to push snow. First time eating **** will be a blast.
Yea, that is a similar hub motor. I will try your saturation suggestion today.
My cells are 3.6v fully capped off the cells hit 72.2v the controller has a limit of 72v. I originally tried 13s setup and had low-end torque issues. spent $$$ on a new battery and same issues
Tried the 1600w version to try and keep the costs down but I can’t get it to take any amps. Anything more than 50 amps and I need to ease into the throttle to stop the cogging.
I’m thinking of getting the 3600w version or even trying the 120v version to pump more amps into it.
Really need to test this soon before running out of funds
What firmware are you using?
It was not until FW5.1 that larger motors could pass the foc detection with usable values.
With earlier firmware it was a guessing game for larger motors to get parameters that worked.
Now I just need to push away slightly (wheel is barely moving) before giving full throttle and I run sensor less.
Your 13s should have been fine.
When you say the controller has 72V limit, you mean in vesc tool?
I think you play a dangerous game running that close to 75V.
Your issue should be related to the motor parameters you are using.
How should I be concerned about those voltage spikes? I get over voltage fault @ 72.2v and need to drain .2 for the VESC to pass firmware limits.
@Fatglottis Thanks for your help, I’m getting heat for not hitting the snow yet. These guys are anxious to see me fail. I’m going to throw as much power at this possible till it works. The original idea was to get cheap base price for users. Now we just need to prove the haters wrong.
I literally moved all my shit from the beach house to my parents garage to make this work. The goal is to move to Mammoth and make these with friends. Thanks
I get it, it had no balls, I pushed it to the max before reaching out for help. This started with scooter motors… I kept and power and redesigning around the failures. this is version 9.
I thought it had no balls due to using 48v with 60v motor. I bought the biggest battery I could find in the US trying to hit the mountain opening day. It got here and I am still stuck at home.
