Hello,

Does anyone know how to compile the firmware for the MINI4 ?

Should I do something more than to define "HW_VERSION_MINI4" in conf_general.h and upload the "VES_default.bin" file from the "60" folder to the MINI4 ?

 

Thank you

Hi kb101,

no matter what BLDC you are using you always want low RDS_on FETs (perhaps the better low Voltage versions) as well with the full amount of Cs capable on the board. The small ceramic capacitors are far off their spec when used under low voltages. So using more than needed let you work in the (very) Safe Operating Area instead of "on the rim to crash" like a lot of other overspec'ed electronic.

Cheers

Sam

Anton,
at the beginning you showed a round design for a marine motor application. NEMA seems to be some sizing standard for North America, but can also be found at Asian suppliers. Are you aware of any VESC hardware designs fitting for a NEMA 23/24/34 size motor? Seems like there is a host of BLDC motors becoming available in those sizes (12/24/36/48 V and up to 60 A or so) together with a host of standardized planetary gears as well.

Hello,

Thank you very much for sharing your version. I used it to make a specific vesc for my application in round pcb version. However, I don't understand why I have a wrong current measurement. The false current measurement increases exponentially by charging the motor. I also have a duty cycle value floating switching between -3% and + 3% when motor is not spinning. Do you have any leads so that I can solve this problem? Thaanks for help :)
