I think its the combo of running in snow and no airflow around the motor that made it heat up. I would say given what you said I'm not surprise the motor heated up to 215. Hopefully you havent de-magged it.

any bl motor [ferrous-loss ones like the kontronik tango are excluded] will seriously overheat if run with minimal or no load...
