Hello All,

I am trying to achieve higher RPM by using field weakening mechanism, can anyone here suggest me which parameter helps to achieve the logic, I am currently trying to decrease Id_ref current to negative value ,
but after certain values the motor halts abruptly.

I am doing changes in the current reference just before entering PI loop, I was able to achieve higher speed once my motor saturated like for example initially my motor was getting saturated for 2300 rpm but
once I try to apply field weakening on Id_ref current the speed slightly increased to 2450 rpm.

Have any of you tried to implement Field weakening, if tried can you suggest me which parameter has direct influence on the logic. I am currently using Demo Code for TLE 987x.

Harsha

Hi Harsha,

field weakening has not been implemented with our FOC software yet.
if you have any success let us know!

Best,
Fiz
