TMDSHVMTRINSPIN: Motor parameter estimation in Instaspin

Rishabh, Please make sure the hardware and motor parameters are updated in user.h. Which signal did you captured in scope?

Thanks for the reply.

The signal captured in the scope is line current.

These are my motor parameters:-
#elif (USER_MOTOR == my_motor_2)
#define USER_MOTOR_TYPE                   MOTOR_TYPE_INDUCTION
#define USER_MOTOR_NUM_POLE_PAIRS         (2)
#define USER_MOTOR_Rr_Ohm                 (NULL)
#define USER_MOTOR_Rs_Ohm                 (NULL)
#define USER_MOTOR_Ls_d_H                 (NULL)
#define USER_MOTOR_Ls_q_H                 (NULL)
#define USER_MOTOR_RATED_FLUX_VpHz        (0.8165*220.0/60.0)
#define USER_MOTOR_MAGNETIZING_CURRENT_A  (NULL)
#define USER_MOTOR_RES_EST_CURRENT_A      (0.25)
#define USER_MOTOR_IND_EST_CURRENT_A      (NULL)
#define USER_MOTOR_MAX_CURRENT_A          (1.2)
#define USER_MOTOR_FLUX_EXC_FREQ_Hz       (5.0)
#define USER_MOTOR_INERTIA_Kgm2           (2.12002e-05)

// Number of lines on the motor's quadrature encoder
#define USER_MOTOR_NUM_ENC_SLOTS          (1000)

#define USER_MOTOR_FREQ_MIN_HZ             (5.0)           // Hz
#define USER_MOTOR_FREQ_MAX_HZ            (60.0)         // Hz//modified on 31/08/2021 to make software compatible with 0.25HP Motor

#define USER_MOTOR_FREQ_LOW_HZ            (10.0)          // Hz
#define USER_MOTOR_FREQ_HIGH_HZ           (60.0)         // Hz
#define USER_MOTOR_VOLT_MIN_V             (4.0)           // Volt
#define USER_MOTOR_VOLT_MAX_V             (220.0)          // Volt

#else
#error No motor type specified
#endif

The values match the values given in the Lab Manual.
