TMS320F2800157: Auto-tunning support on F2800157

Part Number: TMS320F2800157

Hello Team,
     We are running a customized PMSM 48V motor with a sensorless and sensored (Hall Feedback) method with Customised MCU
using F2800157.but when to try run with a different PMSM 48V motor(Same specification different motor) every time calibration is required  in user_mtr1.h then only the motor running properly.
Similarly, our competitor facing the same issue but they have implemented the Auto-tunning method to overcome the above issues.
How to do Auto-tuning with Sensorless or Sensored method?

The below procedure usually we will follow :
1) First will try sensorless method to identify the parameters and after that identified parameters will be implemented,
and run through sensored Feedback.
2) once the motor and mcu are calibrated perfectly if try to do it with a new motor(Same Spec) then we have to do a new calibration every time?
 how to avoid the above issue and any Auto-tunning procedure is there to reduce the time of calibration?

    As you mentioned above, you can add a function to do the auto calibration and save the calibration in the code for a new motor, and then use the saving calibration next time.
