On what does the value of resistor r​41 and r55 depend

  1. I tried increasing shunt resistance but the measured current value when I start the motor is very high​.
  2. I am not ​getting the current value accurately.
  3. The motor spins in open loop and when it shifts to closed loop it starts oscillating and draw very high Ampere​

On workbench graphical interface, click on "Current Sensing", set your "Rshunt" value, and click on "Calculate". "Export" will gives you Resistors description. And changing resistors value, it will gives you, according to the Imax Current, the Vout dynamic.

Best regards.

Thanks for your reply.

I did increase the resistor value and it helped me from your reply
