Hi,

I am trying to run a 6 pole BLDC motor using DRV8308 but i am unable to find suitable FILK1,FILK2,COMPK1 ans COMPK2 values for this motor.On what basis are the poles and zeroes selected?

Thanks

Hi Sudeep, in case you're not aware of this, please see Section 3 of the DRV8308 User's Guide. Setting the registers you asked about is mostly a trial-and-error process.

Best regards,
