Motor temperature via winding resistance

If winding resistance be monitored, e.g. at intervals by injecting d-current (or only at idle/standstill), then a resistance increase of 30% (or so compared to what was measured during motor/FOC configuration) can be interpreted as "motor is overheating".

Thx for the input. It will be debated. Frank

I have done some testing with this as it would be very useful, but so far I only got it working reasonably at low speeds. That was without signal injection though. When I spend more time on signal injection for position estimation at 0 speed for salient motors I will have another look.

That would be really cool
