Vesc for 5000kW QS 205 Hub Motor ebike

I am running 3.5 turn QS Hub motor in 16 inch moto wheel and was wondering what would go wrong if I will have ves similar to 75/300 for it? 

Anyone tried yet? 

Would it be possible to run at 100-120 battery amps constant?

Hi Amiran,

 

What voltage is your system? There are some VESC based projects under development that are aimed at up to 20S :)

Hey Amiran,

I am running the water cooled 200A VESC from Flipsky with a QS 205 hub motor on my bike and am having issues with it. I need to spend more time working on the settings because right now I can spin the rear wheel fine with no load but once I load the tire it cogs really bad and will only run for a few seconds before setting a fault. I love the VESC platform and was thinking about trying the 75/300, have you tried it yet?

One other note, I havent been able to get the hall sensors working yet so I am running it completely in sensorless mode. Hopefully this week I'll be able to adjust the settings and get the hall sensors working, if I get it going I will let you know

Good luck, let me know if you tried it yet

Were you able to run qs205 50h on vesc? What does the programming process look like. How it works. Honestly, I am considering the vesc100 / 250 or 75/300 version. What is the phase current for these versions? Is the hybrid function working properly? Is it possible to program a start using the hall and then switch to sensorless? What are your observations? So far I have used kelly, sabvoton, ASI, Votol, Kungteng, nuclear, etc. Thank you for your help

Have been running my controller hardware with qs205 v3 for three years now.  26s battery, 100A batt, 300phase. Can push more amps but the bike pops the wheelie above 300A, so feels unsafe.

QS205 would overheat after 10 min of hard accelerations at around 30C ambient temperature, so I added hubsinks and statoraid - it helps quite a bit.

Here is my process setting up any new motor and it would be similar in the vesc tool:

Hi Vadicus, I have the Spintend 100v100A for my qs 205. there's some cogging at low RPM in sensored mode, wondering if you've had that problem.

What aer your settings in FOC, like open loop erpm and sensorless erpm etc?
