I know this sounds like a quesiton 20 years ago. but i'm just in the need of such a technique to measure the flux position in an induction motor. i tried some hall effect sensors, it's really hard to calibrate the two sensors to be 90 degree apart. I'm also trying to use the coil to get the derivative of flux, but i need to have further signal processing. Is there any commercial product or practical ways of doing this?

thanks in advance.
