I would like to use current sensing for implementing FOC control of my BLDC motor. To implement this in my current setup I need to know the shunt resistance and op-amp gain used in the EV6540. I’ve looked at the schematic but need help understanding it.
- Is there a shunt resistor? Or do I need to include one outside of the board?
- Is there an op-amp used for the current sensing outputs? If so what is the gain?
