tHi Team,
we were evaluating the evaluation board of DRV10970 with our motor.
During experiment we found that the current waveform of motor phase is good at 70% duty cycle but getting worse at full speed. what will be the root cause and how can we overcome this commutation issue. for reference please refer below waveforms.
1. waveform with 70% duty cycle ( yellow - hall sensor , pink - phase current)
2. waveform with 100% duty cycle ( yellow - hall sensor , pink - phase current)
