General discussion

Hello,

over the last two years, ive built a gokart with four individually driven BLDC escooter motors. the motors are stated 10S, 350w. im running them on 13S 500w ebay controllers.

i built a custom 48AH 14S15P battery, so the motors are already overvolted. im having trouble with the motors being stupidly loud and in general, i think it could be faster.

(it goes 30mph down a hill if it feels like it :/)

I am using a MY1020 motor with a Flipsky VESC controller in FOC mode for a mower project. I am new to all of this, so I assume my terms and basic understanding of VESC may be wrong. I have successfully set up VESC and ran the motor for hours under load. My only tweaks to the setup wizard settings were to increase the motor current and limit the ERPM. I run by setting the ERPM to a value I am happy with. All seems to work well enough, but I have a couple questions:

I have a Flipsky and I cannot find the proper settings for the Obarter D5 in the VESC tool. The wheel motors are 2500w each, from what I understand. The motor FOC I find in the wizard is for 400w. If I am reading this correctly.

Can somebody point me in the right direction so I don't blow anything up?

Hey guys
Hope all of you are doing well

I was looking into vesc-based Flipskey controllers to run my 72V 6kW PMSM.

Ok, so I just built a VESC 4.12 a few days ago.  I've been trying to get it up and running with VESC Tool via USB.

Hi everyone!

Looking for some VESC tuning help, willing to pay for it as it is a product that I am selling. 

I have an electric wheel barrow motor that i am using on a tugging device, essentially its pulling heavy loads at low speed. I want to use PID speed mode and set my ERPM limit at a walking pace cause i don't want it to be able to go any faster. When i am at 5k erpm and i try and push it faster it actively brakes to keep the motor at 5k erpm, however when i get up to 10k erpm and try and push it faster it allows me to push well past 10k erpm even when i let off the throttle completely. Then when it comes down below 10k erpm it will resume its braking.

I have 2x identical setups having the same problem:
2x Flipsky FSESC 75350 and 2x Flipsky 85165 200KV 8KW continuous 19KW peak BLDC motors running sensorless on 50V, FOC, Current control, 300A limit, 450A ABS Max.
This is a dual outboard boat setup.

Auto-detected FOC values on each:
Setup 1) R 6.4, L 7.59, LQ-LD 0.90, Flux Linkage 5.38, KP 0.0076, KI 6.36, Observer Gain 34.56.
Setup 2) R 6.8, L 7.66, LQ-LD 0.68, Flux Linkage 5.61, KP 0.0077, KI 6.75, Observer Gain 31.79.

Hallo ich bin neu hier und habe mir für mein DIY E Foil einen Regler Flipsky 75200 mit Wasserkühlung und den Flipsky Motor 3600 mit der passenden Flipsky Remote VX3.

Nach dem das gleich beim ersten mal geklappt hat das Programieren beider komponeten .

Hello,

I am using (somewhat modified) VESC on an unmanned aircraft. We are running a trampa mkvi hp and a 220kv brushless outrunner, sensorless. I've set the startup settings so that they limit startup current only, there's no open loop at all afaik. I've tested thousands of starts, stops and reversals on the ground, and have been building hours in the air on around 10 separate aircraft.

Everything has been going well, except we had one aircraft that ran into 2 startup failures in the air, on the same flight.
