PMSM Sensorless Control Using InstaSPIN (DRV8305) to BOOSTXL-DRV8301

Hallay

Hello Expert

 

There is a video to teach how to use PSIM file and BOOSTXL-DRV8305 to spin motor.

I want to use BOOSTXL-DRV8301 to instead BOOSTXL-DRV8305.

Change ADC arrangement in PSIM file according to DRV8301 Pin out.

However motor can't SPIN normally.

Can anyone tell me how to solve it?

 

thank you

Hi, Hallay,

Would you send your PSIM schematic over so we can check the details?

Do you have a compatible XL LaunchPad? Have you configured the LaunchPad according to TI's user guide?

 

Would you describe with more details about how the motor's spinning is abnormal?
