Hi All,
I want to run the PMSM motor using micro-controller dsPIC33F. the motor should be run in such a way that initially it may operate in open loop, of course using Space Vector Modulation (SVM), and then it will go in a closed loop where it will read the value of feedback current by ADC, and should be operate on a constant speed using PID control.

I've already designed schematic and all, but can't run the motor in open loop using svm.

if any of u have d solution, plz tell me.

You could input the fixed Ud and Uq(0 Ud and a constant Uq), then increase the input electrical angle from 0 to 360 degree, then the motor could run in open loop mode.
