That looks exactly like a shorted phase. Don't run that motor again, you might damage other stuff if you do. Give Neumotors a call to get an estimate on price and turnaround time.
Next, if your motor ever goes over 200, check everything over for problems before using it again. I am with lutach as well, send it to neu and live with the piece of mind it will be fixed and running correctly.
It looks like something jammed the rotor (debris inside the motor, or just a really heavy load) and a stantionary rotor is just about a short - the only thing limiting the current to the motor is the ESC capability, battery capability, and wire gauge.
That motor is smoked. I did the same thing. Bad solder joint and it came off the track at 300 degrees with smoke pouring out of it. At some point it is going to fail if it hasn't already demagnetized.
Neu will replace the motor, but it will not be under warranty as the failure was caused by something other than workmanship of the motor. They have a good replacement program though. 50% off any new motor of your choice.
