Part Number: TMS320F280025C


Iam using TMS320F280025C + DRV8343.

Inputs entered in coding is based on the motor parameters.

1.I want to increase the torque to 6 Nm.

what parameter should i tune to increase the torque?

    Assuming you are using the lab based on InstaSPIN-FOC. Please take a look at the lab user's guide. You can increase the maximum current according to the motor. And also take a look at the datasheet of DRV8343 to increase its current limitation by setting its control registers. 

    // the maximum current value of the motor, in A
    #define USER_MOTOR1_MAX_CURRENT_A (9.5f)

    1.Generally, at input side current drawn with respect to load/torque variation, if it's more torque it drawn more current, in our cases motor drawn more current in input side but estimator window shows very less torque (E.g:- at the time of 22A motor delivers around 0.5Nm but estimator window shows 0.192Nm only).

    could you please clarify this.

    You may check if the motor and hardware parameters are set correctly according to the system you are working on. The calculation torque is fully related to these parameters.
