I am using BLDC sensor-less FOC for motor control, I wanted to achieve 4000 rpm at 11V, But the motor I am using is getting saturated to 2300 rpm, when I increase the voltage speed is able to increase.
But, the requirements are to achieve higher RPMs with 11Volts. is there any software based restrictions to the stated problem. I have tried changing multiple parameters to fetch results but nothing seems to work out.

I suspected if there is limitation on Hardware but the Hardware vendors were able to run the motor for 6000rpm at 11Volts. So I feel the software restriction is existing. Can you suggest if any parameters is
to be changed to run the motor at higher rpm.

I have tried few parameters like Speed Limit, Reference Current. And I have modified other parameters with respect to motor parameters? Is there any limitations on Demo Code?
