This is the latest result (5 minutes old ) of my 30F controller.
Sensored startup, then sliding transition to sensorless. Full UN-interrupted sinewave output on all 3 motor phases.
The motor control algorithm does NOT use the motor inductance / resistance, it has no knowledge of these parameters (unlike
Field Oriented Control )

The transition to sensorless is around 10V, you can really hear the change in tone (around 25 sec in the video).
For the video I increased the rpm where the transition is made to show the sound difference between
sensored and sensorless. The transition can be made at a much lower RPM (but then the transition
would not be very audible)
