Hi Team,
May I ask for help? This concern was a continuation of the other post below:
(+) DRV10983: getting stopped in open loop - Motor drivers forum - Motor drivers - TI E2E support forums
We still got a response from our customer as shown below:
"as per advise, we have made a PMSM motor and still facing the issue
To brief the problem - we are using EVM of DRV10983 to rotate the BLDC motor of the ceiling fan, but we couldn't rotate it at the desired frequency/rpm.
Earlier we were using reluctance motors and as suggested we designed a new PMSM motor. Even, in that also we are facing a similar issue.
Please find the attachment "BLDC-PMSM_AsPerEarlierSuggestions.pdf" we used by following the instructions in the below training videos,
Part-1 training.ti.com/how-spin-drv10x-family-devices-part-1
Part-2 training.ti.com/how-spin-drv10x-family-devices-part-2
BLDC-PMSM_AsPerEarlierSuggestions.pdf
Kindly help us! We are looking for a motor to rotate at 370rpm but it is not exceeding 210rpm. Also, as said in the part-2 video can you share with us the tutorials which explain the significance/guidance for tuning the other parameters."
I hope you can further assist us. Thank you so much.
Kind regards,
Gerald
