Hi everyone,
Long time lurker and a big fan of the work you have done!
Disclaimer I am running custom firwmare and not using SimpleFOC, but this forum has been a great knowledge base in learning about FOC and I am hoping someone here can guide me.
I’m facing an issue on a custom board using a DRV8323 a STM32G4 and a CubeMars RO80 KV105-lite motor. The motor is whining even when I command Iq = 0 Id = 0. Im using SVPWM and alternate reverse sequencing, which essentially means all 3 top side FETs are on 50% of the time and all 3 bottom side FETs are on the other 50%.
If anyone has any clue as to why this could be happening I would appreciate it very much.
I’m currently also in contact with Texas Instruments support via this post:
The posts contains much more information about the measurements i have already performed.
If this post is not appropriate for the SimpleFOC forum I will happily remove it, but I am at my wits’ end trying to solve this issue.
