That beeping is to let you know that the battery is still plugged in; it also doubles its function as a lost model alarm. Unfortunately, it is normal for the motor to overheat while it is beeping for some time. The quads' motors do it too unless you lower the beacon (beeping) strength and intensity. I don't know if you can adjust the beacon parameters in 330x ESC though. Hopefully the motor is not damaged because that smell was from enamel burning off of the coils (plus heat damaged magnets).
