Hello,
I am controlling AC Induction Motor in Sensored FOC Mode. DSP used in this project is TMS320F2810.
Induction motor which i`m using is high speed one up to 12000 RPM.
I`m able to run induction motor up to 12000 RPM in NO Load condition with Sensored FOC with out any issue & it`s taking nominal current.
Now, "IDRef" which is reference value for ID Loop needs to be reduced when we are going above rated speed of the motor. which i`m doing with a field weakening algorithm.
When i`m loading motor up to it`s full capacity (24Nm), my drive is taking higher current then it`s specified rated current.
I`m able to run the same motor with V/F Control algorithm within rated current limit.
please suggest me how to set IDRef according to RPM?
Is it possible that for any RPM IDRef value is different for Load & NO Load Condition.
Is IDRef Value related to load on the motor?
