General discussion

I am a beginner with VESC. I have been trying for a few days to operate a VESC and an 800kv 4250 motor with an e-bike grip throttle, but cogging occurs and it does not function properly. I completed the motor and input setup based on information on the Internet. As the motor ran correctly during Motor Detection, I believe there are no problems with the motor and VESC. I suspect that the ADC setup is not correct. However, I could not find a solution to this problem. If you know how to solve this problem, please let me know.

Hi I am looking at the feasibility of driving BLDC motors (probably 4) from a 24v 150A alternator (around 3kw total) - the diesel motor driving the generator has a simple mechanical governor

My electronics knowledge is not strong and I am looking for guidance as to whether this is feasible.  Can the VESC software / hardware really only run from a battery or can it be run directly (and or with a battery in the circuit) from an alternator 

Hello!

I am using 4x hub-motor wheels with hall-sensors. I setup using the VESC-tool and its working OK'ish using the "Duty Cycle" control. 

However, i am looking for a control type for direct RPM control. Which control type should i choose?

From what i can see there is not a spot to select brushed dc motor from the app, is this something i just missed or in a different tab?

From the pc application its under general->motor type->(BLDC/DC/FOC/GPD)

Moble app only seems to offer various sizes of inrunner or outrunner options.

Would the type of controller have an affect on this? tried a few different vesc based controllers.

I'm not seeing any CAN commands for setting motor configuration values, am I missing something? Specifically, I'd like to be able to set the PID values for the position and velocity controller, Should I just be adding commands to the firmware for this myself?

Thanks!

I have a static torque control application that I am hoping to implement with a VESC and a permanent magnet brushless motor with Hall sensors.

It would be a subsystem in a control loop that would continuously adjust the torque applied to a torsional spring.

Most of the time the torque would be constant, so the motor would not be rotating. Both positive and negative torque would be needed.

Is this even possible to do? If so, how would I set up the VESC?

If it is not possible with a permanent magnet motor, how about an induction motor?

Hello,

I've built an electrical winch for paragliders with a 12kw hub motor. It is operating with a VESC 75/300.

Today we wanted to test it's drag force before we are actually going to use it to launch a real paraglider.

We attached a "Quad" (a motorcycle with 4 wheels) to the line and started pulling. To measure the drag force in kilogram (or daN) we were using heavily the brake of the quad. 

Hi,

new here not sure if this is the right forum category for this, anyways . . 

I have the older version of the Flipksy 75200 VESC which I blew some components on the back of the board when I tried to run it on BLDC mode instead of the normal FOC. It looks like they are direct MOSFETs? 

Does anyone know where/ and if I could purchase new ones? The number on them is IYR 7769 JHZU 1332, with the Y looking more like a upside down triangle with a vertical line through it. 

Hey folks i'm a little stuck.. I was adjusting the shutdown mode on my VESC based esc and I moused wheeled to always_off without realizing I did it and wrote the config.. Only realizing my mistake after I reviewed my settings. I'm stuck with esc shutting down right away. How do I reset this?
