Motor Identification process

Hi

I am using Teknic M2310P-LN-04K motor & TMS320F28069M launchpad with 3PhGanInV Inverter board.

 I am doing Motor identification in Altair Embed. I am using 3PhGanInv inverter board instead of DRV8301 booster pack, so I have changed ADC filter(Hz), ADC configuration and ADC Full scale voltage & ADC full scale current.

I am trying to do this program referring to this video: https://www.youtube.com/watch?v=eri3N-klpLI

In this video Est state is changing and motor is running while identification, while in my case  i am not getting motor parameters, motor doesn't Spin and ctrl state and Est state changes from 1 -1 to 3 - 13 respectively without detection of parameters.

Can anyone please help me out to solve this issue ?

    Hello Swapnil

     

    Here is the new setup and now we measure the parameters using a LCR meter and current control.

    Attaching here two vsm files and a jpg for your reference. This should help you check all the values for parameters to be set correctly for F28069M with 3PhGanInv

    We are developing a complete eDrive add on for 2021 release which will include all latest motor control examples and documentation.

    Hope this helps. I recommend that you also go through the book 'Applied Control of Electrical Drives' for a detailed view of Real-time embedded and sensorless control of motors with F28069M and Altair Embed (VisSim)

    Hi Swapnil

    Here is a revised version of Embed InstaSPIN parameter estimation for the 3PhGanInv board working with the Teknic motor. This shows the parameter ID and then ends on speed control FOC.


    Attached the compile and debug files along with a InstaSPIN logo image.

    Go to compile file>FOC_FAST>Main motor control and then ctr+right click on controller block which may have file path written on it. Change the file path to the local directory where you save the logo image.

    Make sure the "conv_on" button is OFF before running simulation.
    Also on the launchpad F28069M board make sure jumpers 1 and 2 are OUT, otherwise USB power goes to the MCU.

    This should resolve your query.
