Part Number:BOOSTXL-DRV8301
Hello
I tried to use the LAUNCXL-F28027F + BOOSTXL-DRV8301 to control the speed of GT2820/04 motor. the motor's parameters: Cell count:3-4S, RPM/V=1460, no load current=3A,Max RPM=17000, Max current=48A, number of poles=14
Max speed that I need is about 3000 rpm. I ran lab2b and lab2c to identify the motor's parameters. in these labs when I changed the "SpeedRef_krpm" the motor's speed didn't change. why does it occur?
below shows the achieved result with vdc=13v:
#define USER_MOTOR_NUM_POLE_PAIRS (7)
#define USER_MOTOR_Rr (NULL)
#define USER_MOTOR_MAGNETIZING_CURRENT (NULL)
#define USER_MOTOR_RES_EST_CURRENT (1.0)
#define USER_MOTOR_IND_EST_CURRENT (-1.0)
#define USER_MOTOR_MAX_CURRENT (8.0)
#define USER_MOTOR_FLUX_EST_FREQ_Hz (20.0)
#define USER_MOTOR_Rs (0.01457627)
#define USER_MOTOR_Ls_d (2.113534e-09)
#define USER_MOTOR_Ls_q (2.113534e-09)
#define USER_MOTOR_RATED_FLUX (0.01733333)
when I use thses achieved parameters an error appeared as "USER_ErrorCode_ctrlFreq_Hz_Low". and when I increase the Ls_d and Ls_q value, this error dosen't occure . but I cant change it's speed. How can I solve these issues?
Regards.
