currently I’m trying to set up dual motors in BLDC mode with hall sensors enabled. When I do a motor detection the ‘‘Detected hall sensor table:’’ is always empty though.
The sensors do work in FOC mode, but I’m afraid of running FOC on 4.12hardware.
Same behavior for both motors, am I missing something here?
Possible bad advice warning
Can you do the detection in FOC, write down the hall values and then manually enter them once you change to bldc mode?
I have no idea if this would work or not, but that’s what i would try.
Probably not a good idea, because the values from FOC mode are 3digit values, while the ones from BLDC are 1digit.
Haha i’m glad i added the disclaimer then
@Tony_Stark knows stuff and things about bldc mode
Or sensorless bldc. Sensors are for wussies anyway
Not an option, mountains and hills everywhere where I live
Sensor detection looks successful in the screenshot tho. You set it to hybrid mode right? Have you tried spinning up the motors after applying everything?
Is your sensor switch on 3.3V instead of 5V?
Nevermind, just saw this is a 4.12, but leaving this here to help others reading in the future
Have you verified with a meter or scope that the sensors are actually working?
Indeed they were detected successfully just not shown in the line I highlighted… silly me
thank you made me fix this much quicker
I’m using sensored mode, should I switch to hybrid?
Yeah use hybrid. Sensors dont work well at high speed.
If you experience some stuttering on takeoff there is a setting in one of the advanced tabs called hall sensor extra samples. You can try increasing this to 4 or 5 to clean up sensor noise
Since they got rid of this in the latest firmware, anyway to get around it?
I’m definitely still experiencing cogging on startup unless I use sensors up to a higher erpm… which is sketch.
Not that I know of. They moved it to the sensor table in FOC. I run FOC now days as the performance is better after tweaking. I definitely miss the noise though
Alright after AVS I need to mess with FOC detection values. Cause I don’t like this cogging.
Honestly though the updates don’t affect BLDC mode afaik so running an older firmware is the best option for BLDC. Just means the stupid phone app won’t show stored telemetry
