Hello,
Currently i am using BLDC Foc sensorless example with TLE9879 evaluation kit to drive my BLDC motor
My BLDC have a max operating speed of 10000 rpm.
I wanted to achieve 9000 rpm whatever the power supply voltage (10 V, 13V or 16V)
My issue is that the motor speed is getting saturated to 4000 rpm at 13V. When i increase the voltage (16V) i'm able to reach 6000 rpm
Is there any limitations on Demo Code?

Regards,

Hey Bendr,

Any answer to this? Having the same problem. It seems the max speed does nothing.

Regards,
John
