Hello together,

Hi everyone, 

I recently purchased an AMT203 absolute position encoder and want to connect it to a Flipsky 4.20 ESC equipped with VESC firmware.

I took inspiration from this video: https://www.youtube.com/watch?v=8CcqD5sw90U&t=190s&ab_channel=BenjaminVe...

Doing some research, I found this wiring diagram and it seems the best option. If anyone has any experience with this, any assistance would be much appreciated! Thanks very much. 

Hello.

Hello,

for a new project i decided to use BLDC motors, this is the first time i work with BLDC motors and now i can't get any further.

I set up the motors and input with the wizard as described in many videos.

I use a Flipsky 6384 190KV with Flipsky Mini FSESC4.20.

At 44V and 190KV the motor should make 8360 RPM?

I measured the RPM and the motor is only making about 2500 revs.

In the most of the videos mention that incorrect settings can destroy the VESC, I don't want to work with try and error here.

Hi folks.

I'm trying to port https://github.com/vedderb/bldc_uart_comm_stm32f4_discovery to ESP32 but I'm with a doubt. I basically updated the files for the newest version and noticed the following:

I'm hoping I might find some answers or help to this issue here on this forum. I hope this is the right place to ask. The MOSFET in question is labeled mcac80n06. I've tried to source the original chip but as with most transistors it's extremely hard to find them. I've tried contacting the original manufacturer but no response. 

Hi guys, 

I am using my VESC and BLDC motor as a variable brake, and need smooth operation at low speeds, however due to the torque ripple of the motor I am experiencing some problems.  

I am wondering if anyone has looked into or used any anti-cogging algorithms like those discussed here https://hackaday.com/2016/02/23/anti-cogging-algorithm-brings-out-the-best-in-your-hobby-brushless-motors/ ?

I have a few (8) of the Flipsky Mini FSESC6.7 ESCs.  These are being used in a robotics application and need to be controlled over a CAN bus.

I'm trying to run a 4 pole inrunner with PID Speed Control using ADC input with a potentiometer. I have properly mapped the potentiometer voltage range. The problem is that the PID control sets the motor to maximum RPM at only 25% of potentiometer travel. The remaining 75% of travel shows up correctly in the ADC bar as the voltage rises, but the motor is steady at full RPM.

In PPM mode, there is a field for maximum PID ERPM. Is this feature missing with ADC mode?

Hi Guys,

I have my motor running on the Vesc MK6 controller and everything works perfectly until I unplug the USB cable on the Vesc.  As soon as I then send a command to turn the motor via CAN the motor oscillates back and forth.  If i plug the USB cable back into the board and connect to my laptop, as soon as the computer "chimes" to recognise the connection the motor returns to normal operation before the Vesc tool is even connected.

Any ideas please!

Thanks in advance.
