hello
my name is sean .
I have a question about phase voltage waveform of DRV8307.
When you measure the phase voltage to drive the BLDC motor in DRV8307 EVM B'D, it is as follows
.
In general, when bldc motor is 120°communitation, phase voltage is you know in a trapezoidal shape.
Please be the shape of the waveform to explain the other reasons.
Best regards
sean
