Greetings! Here are my motor parameters:
#define USER_MOTOR_TYPE MOTOR_TYPE_INDUCTION #define USER_MOTOR_NUM_POLE_PAIRS (3) #define USER_MOTOR_Rr_Ohm (69.7)/*calculated by formula from internet*/ #define USER_MOTOR_Rs_Ohm (56.2)/*measured with multimeter*/ #define USER_MOTOR_Ls_d_H (0.219)/*measured with LC meter*/ #define USER_MOTOR_Ls_q_H (0.219)/*equals to USER_MOTOR_Ls_d_H*/ #define USER_MOTOR_RATED_FLUX_VpHz (0.8165*230.0/50.0) #define USER_MOTOR_MAGNETIZING_CURRENT_A (1.97) #define USER_MOTOR_RES_EST_CURRENT_A (0.14)/*10% from USER_MOTOR_MAX_CURRENT_A*/ #define USER_MOTOR_IND_EST_CURRENT_A (-0.14))/*- 10% from USER_MOTOR_MAX_CURRENT_A*/ #define USER_MOTOR_MAX_CURRENT_A (1.4) #define USER_MOTOR_FLUX_EXC_FREQ_Hz (5.0) #define USER_MOTOR_NUM_ENC_SLOTS (NULL) #define USER_MOTOR_INERTIA_Kgm2 (2.12002e-05)/*incorrect value taken from another example*/ #define USER_MOTOR_FREQ_MIN_HZ (2.0) #define USER_MOTOR_FREQ_MAX_HZ (50.0) #define USER_MOTOR_FREQ_LOW_HZ (10.0) #define USER_MOTOR_FREQ_HIGH_HZ (50.0) #define USER_MOTOR_VOLT_MIN_V (100.0) /*not sure*/ #define USER_MOTOR_VOLT_MAX_V (230.0)
So here is what is happennig when I start the procedure-> I have 2 reactions - first one the motor makes a few rotations, stops and starts buzzing. The second outcome is a short circuit after a few rotations. I `ve tried different values for USER_MOTOR_RES_EST_CURRENT_A and USER_MOTOR_IND_EST_CURRENT_A as the datasheet suggests. I`ve watched one of your example videos and the motor there was spinning through the entire procedure(I am not sure because of the low quality). I`ve done the sygnal chain test and there my motor is spinning and I think everything is fine. Can you give me an idea what to change so I can ID my motor?
Thanks!
