Re: Shunt Sizing

I decided not to make this change. I did some more looking and realized that the issue is 100% noise, not ADC resolution. When the motor isn't turning and there is no current being fed to the motor, the current page shows +-1A on all the coils, with about .4A of higher frequency noise within that l...

Current issues DRV8302 fault

Hello, I recently have a very big issue about current. I self made a vesc and test it on the vesc-tool. I used the firmware 3.29, hardware 4.12. The testing software is vesc-tool version 0.82 not bldc-tool. I just connected the motor and press the real time data button. When I pressed the bldc detec...

Position Control Acoustic Noise

Hello, When I am using the AS5047 encoder position control of the FOC mode, the BLDC motor keeps making acoustic noise. I noticed that in the Benjamin encoder position control video, the BLDC motor makes acoustic noise as well. Is there any way to minimize the acoustic noise? Thank you very much Mic...

Encoder detection not working

Hi, I'm working on a VESC encoder position control project. I'm using Maytech 6374 motor. My motor does not work with VESC encoder detection. I'm using a 1000 pulses ABI encoder. I set the encoder counts to 4000 and the encoder mode to ABI mode. The encoder reading is giving me a 0-360 degree readin...
