DRV8323: Please help to check waveform

Part Number: DRV8323

Hello Sir:

We are not familiar motor behavior or motor driver.

There has current waveform from one phase of motor.

Would you please teach us how to improve the sine wave waveform?

Or do you have a guide to share with us?

Looking forward your feedback.

Thanks a lot.

Hey Statham,

Thank you for your patience.

In order to provide meaningful feedback, I would like to ask some preliminary questions to understand the setup.

What IDrive setting are you using? Are you using bulk capacitors at VM if so what size and how many? Which PWM mode are you using?

It would be helpful if you could provide us with a schematic to better understand what is happening.

Thank you.

Best Regards,

Akshay
