Hi.I'm driving a PMSM with FOC (Workbench file attached for reference) with MCSDK 6.3.0 in torque mode.Main parameters:1400 Hz electrical frequency max -- therefore 16 kHz PWM100 Hz mechanical frequency max~0.03 mH line-to-line inductance~9 V/Hz Kv 0...

Hi everyone!I'm evaluating STSPIN32G4 for driving a small 6 kRPM 28-pole PMSM (up to about 30A load current - it's driving a propeller, 0.06 mH inductance, about 160 kV). Generally the performance is quite good, but I have noticed frequent STOPLL fau...

Hi @GMA,Thanks for pointing in the right direction.Indeed, Trise and Tnoise are detailed in "Current sampling in three-shunt topology using two A/D converters" in the documentation, in cases 2 and 3.I was able to increase the max speed somewhat by ad...

Hi @GMA,Thanks for the response!The version is MCSDK 6.3.0.Without overmodulation I don't see the issue indeed but I'm also unable to reach the required speed without it (it goes up to about 4.8 kRPM wihtout overmodulation and our application range i...
