Hi,

What would be the best way in Motorware FOC to detect one rotation of the BLDC motor shaft?

Thank you.

For sensorless-FOC without any position sensor, you can check the rotation by rotor angle, every 360 degree (_IQ(0.0)~+/-_IQ(1.0) in motorWare) means a rotor rotation.

Hi Yanming,

Thank you for your reply. I got the motor electrical angle from the EST_getAngle_pu function and it worked.
