  • DRV8305: BEMF value in DQ reference frame

    TI Thinks Resolved
    Part Number: DRV8305 Hi, I have measured the back emf waveform between two motor terminals (phases) and it looks like so: So I have 9V peak-peak (4.5V Amplitude). It is sine, but in D-Q reference frame it will be constant DC waveform (at a specific speed…
