Other Parts Discussed in Thread: MOTORWARE
I used lab 2b to get the values of PMSM motor resistance as 0.32ohm and inductance (d and q) as 0.00092 Henry ans 0.064 as back emf constant. However, if I use these parameters, 2 out 5 times the motor stalls at startup. If I use the values of 0.16 for resistance and 0.0032 for inductance (values I found by accident -related to other motor), the motor works fine. I tried matching current loop parameters by changing PI coefficient calculator (changing scaling factor for Kp calculation), but still phenomenon continued. In view of this, I wanted to know if not only PI coefficient theta computing function in code uses these values? If yes, how can I check what is happening?
