Default brushless inrunner

Is it possible that running an inrunner brushless motor, without the fan blade, on a edf, would cause it to fly apart on the inside????
Thanks

Welcome to the forum!

I suppose anything is possible. I think inrunners are rated for very high RPM usually, and you should be able to run it without the fan with no problems. However, I wouldn't exceed its recommended input voltage and only run unloaded for a few seconds at a time to minimize the risk of mechanical failure. You should only need a few seconds for measurements and testing. Otherwise, I can't see the need to run the motor unloaded for extended periods of time.
