Question
FOC: 'alignment electrical angle' and low speed
Posted on March 09, 2017 at 11:11
Hello.
I'm using the FOC SDK (v4.3) with a incremental encoder.
I need to know what, in practice, means the angle placed on 'alignment electrical angle'.https://spostimg.org/y32f6ts1h/Capturar.png
I'm having some problems because I'm using a BLDC motorand at low speed the motorhas a lot of cogging.
Do you have any suggestions to solve this?Throughout the range of 500->4000RPM everything works well! Below 500RPM it is difficult to maintain control. I'm using an encoder with 500ppr on a motor with 2 pairs of poles.
Do you have any idea?
Thank you. encoder bldc foc-sdk angle
