BLDC Sensorless Commutation

Hi,

Can anyone tell me how commutation is done using back-emf integration technique at high speeds? I have 2 VESCs running. They both perform very well at upto 200,000 eRPM. If anyone can help me understand how it is done since we only have 1-2 integration points.

Thanks.
