TMS320F2800157: Torque control mode implementation in DRV8353 with a 48 volt HALL motor

Tool/software:

Hello team,

I am working with the 48 volt HALL motor in the torque control mode of the DRV8353 with the F2800157 launchpad..

Using the DRV8353 and F2800157 launchpad, I was able to operate the 48 volt HALL motor in speed control mode with feedback, reaching its maximum rpm.

Although I have switched the motor control mode in motor1_drive.c from speed control to torque control, I am still unable to operate the motor in torque control mode at minimum load and I need to submit speed_ref values.

Please advise what changes I should make to the universal motor code in order to operate the motor in torque control mode.

Regards,

Kirana H P
