Hi guys, Does anyone know how to translate hall sensor values from BLDC to FOC? For example, my current hall sensor values under BLDC is: -1, -1, -1, -1, 1, 3, 6, 4 and I want to input this value into the hall sensor table under FOC mode in such a way that it would understand. Based off of some research, I know that a -1 or 0 value in BLDC is equivalent to 255 in FOC. But what about for other values like 3, 6, 4, etc?? Is there a conversion table available to show which values in BLDC corresponds to values in FOC?
My apologies in advance if this is confusing but reason why I am asking is because for some reason, I am able to get sensored mode to work in BLDC by plugging in the hall sensor values directly. But when switched to FOC, the hall sensor detection comes out failed and no values is generated for me to plug in directly like in BLDC. This is why I am asking to see if the hall sensor values from BLDC can be translated to values used in FOC so I can run it in sensored mode in FOC.
here’s some screenshots of what I’m referring to
this is under BLDC mode. The hall sensor detection shows “failed” but I was able to plug in the values from the generated value and got it to work
this is under FOC mode. Again the hall sensor detection “failed” and this time, there weren’t any values generated so I was wondering if I could use the equivalent values from BLDC to plug in to the FOC hall sensor table to get it to work. Does anyone know how to translate the values?
