Hi

I'm Shundai.

I bought a B-G431b-ESC1 and connected BLDCmotor and DC12V

Using the board, I want to know how to drive a BLDCmotor by 3-shunt resister or 1-shunt ( nothing positioning sensor(HALL, ENCODER) and 3-Phase CT sensor ) .

I will modify the circuite of between 3-shunt terminal because This board doesn't support a 1-shunt sensing.

Please teach me how to drive these method.

Thank you.

I guess you don't have to solve this problem anymore, therefore I consider this post closed.
