Issue in Sensored BLDC motor driving

Hello All,

Good Morning!!!

I have developed 12V and 24V BLDC motor driver with max current upto 20A

The driver is working fine. The efficiency is good.

Sometimes it is giving the issue. Sometimes once I turned on the power then suddenly blast happens and current reaches 70-80A.

Please suggest me remedy over this issue. My design is still not getting approved just because of this issue.

Please let me know if you will need more information on it.
