Is there a way to determine the rotors position (angle) , given the 3 stators signals of the induction motor? Accuracy required is 0.05 degrees.

A resolution of 0,05 ( 1/20 ) degrees over 360 degrees yeld 7200 steps.
A programmable rotary incremental encoder can do the job.

I do not wish to use any sensor for feedback as there are constraints in mounting. So, I have three current signals and I need the angle.
