is there any difference between commutation sequence for a delta-winding BLDC and wye-winding BLDC?

Hi everyone

recently I am working on a BLDC motor which has a delta winding stator. is there any difference between commutation sequence for a delta-winding BLDC and wye-winding BLDC? I did not find any document for a Delta-connected motor and I can not understand commutation sequence for it. is there any one explain it for me?

Hello @shirini!

I found two links that could prove useful for your inquiry. The first one makes an extensive description of the Delta winding connection of a BLDC Motor, and the second one explains commutation sequencing in a lot of detail:

https://lucidar.me/en/actuators/commutation-for-bldc-motors/

Finally, I’ll leave an extra link that explores motor controlling with one of our Microcontrollers:

I hope this helps,

Edwin.
