DRV8353RS-EVM: Motor application

Premkumar T

Part Number: DRV8353RS-EVM

Hello Team

I am using hall feedback and a 48V PMSM motor. The motor is operating noiselessly and smoothly.

How to operate the motor so that it runs smoothly. What motor parameter settings need to be set up?

Best Regards,

Hellov Yara AI Shami,

No, it's not running in smoothly.

On the FAST method its working smoothly.

Hi Premkumar,

So if I'm understanding correctly when the motor is slow it is not spinning smoothly but when it's fast it is smooth?

how slow are you attempting to spin the motor where you're seeing issues?

Hi Yara,

Yes, your understanding is correct.

I am running in Low "speedRef_Hz: 60" with accelerationMax_Hzps is: 20.

While increasing the speed noise gradually increasing.

Did you mean when decreasing speed you are seeing noise?

Where are you measuring noise from? Which FET are you using? Which IDRIVE are you using? Do you have series gate resistors?
