Hello Rick,

Thanks for the quick response .I tried to run 24V bldc (77Watts) with serially connected 12V 7AH ups battery. The bus voltage is dropping down to 16V during the motor identification process and the shaft is momentrly oscillating. so I think the problem can be solved with more stable 24V power supply. Opinion please

Thanks

Hi Faizal,

If the voltage is dropping, this could be due to too much current during identification.

There are several posts regarding delta wound motors. I suggest you search using terms like "delta motor site:e2e.ti.com"
