Example MBD Code of BLDC Trapezoidal Sensorless Control S12ZVM

Hi,

I wonder if there is any example mbd code for BLDC Trapezoidal sensorless control of S12ZVM available. I have some difficulty to implement the trapezoidal sensorless control into the mbd code.

Thanks,

Tony

Hi Tony,

No, we do not have such example - BLDC Sensorless.

What kind of issues are you facing ?

Best regards,
Daniel

Hi Daniel,

Thanks for the reply. My issue is about to measure the three phase voltage to get the back EMF, since there is a configuration block for GDU which set the GDUPHMUX to 00. I need to have GDUPHMUX changing between 01,10,11 to connect different phase to the adc to get the back EMF. Is there any method to achieve that? Thanks.

Best regards,

Tony
