Good day to all rolleyes.gif

I am interested to know about direct axis (d axis) and quadrature axis (q axis) in a permanent magnet motor, and there are some parameters such as d axis inductance, d axis current and d axis voltage and similarly for q axis also, as i seen in some of articles, and these parameters are used to identify the rotor poles (unlike using encoders for pole position identification in permanent magnet motors). so can anybody share your knowledge in these topics?

Best Regards,
sharath

Thank You very much for your reply Mr. jomega, the IEEE paper which you suggested to read explains lot of concepts..

I think that this information is the best.
