DRV8312-C2-KIT: Board resistance for DRV8312EVM RevD

Part Number: DRV8312-C2-KIT
Other Parts Discussed in Thread: DRV8312

Hello,

I am working with DRV8312EVM RevD along with Anaheim motor BLY172S-24V-4000. I want to create an accurate plant model for the same in MATLAB. I searched in the datasheet and found that the MOSFET Rds_on is 80 mOhm. Also the R_shunt is 10 mOhm and R_tot_shunt is 5 mOhm. In wanted to know the overall board resistance for the DRV8312EVM board which I need to consider apart from the motor resistance while the motor is spinning.

    For instaSPIN-FOC project, we don't need to consider the board resistance which is included in motor stator resistance using motor parameters identification, so we don't have such data about this board. You may refer to DRV8312 datasheet to calculate the overall board.
