Got a broken Dewalt DCG414 angle grinder to look for the issue.
It has a 54V BLDC motor with builtin ESC mfr P/N: N599252.
The only option is to buy the ESC with the motor and the trigger circuit for ~180 GBP...
I removed the ESC from the motor. The ESC is potted with some PUR resin, so I started to carefully remove it.
It turned out that the low side MOSFETs were blown.
