Hi I use TMDSHVMTRPFCKIT(F28035).

BUILDLEVEL 4,

DlogCh3 = (int16)_IQtoIQ15(clarke1.As);
DlogCh4 = (int16)_IQtoIQ15(clarke1.Bs);

In pdf, phase A&B waveform is clear.

But in my test, clarke1.Asand clarke1.Bs waverforms don't look right.

what is the reason? help me

Which motor and lab project are you using? This is a normal waveform if the motor is a PMSM, it did not have any problem. The waveform depends on motor model and control, most motors didn't have pure sinusoidal BEMF waveform.
