Oskar, on your autorotation to landing comment, you mentioned "closing the throttle" (
); my assumption is that means cutting ALL power to the EMRAX 228 motor from the drive. In such a state, I'm guessing it is neither 'torque control' or 'speed control', but does the drive still somehow know the rotor RPM (stator to armature relative position)?
For example, what happens if you close the throttle, but then decide to re-engage power SLOWLY to the rotor until back up to full power?
It would seem, in that scenario, that descent would be slowed as power was added.
I'm thinking the motor and drive must still be communicating (when throttle closed) so that the drive knows when/how to 'sync up' the motor if you were to re-engage.
Do you have a rotor tachometer?
Thanks again for sharing info on this cool experiment !
