Other Parts Discussed in Thread: MOTORWARE
Hi,
I try to evaluate the TMDSHVMTRINSPIN Kit with F28069M CPU card.
My motor is a 250W water pump
With the InstaSpin-FOC GUI is was able to identify the motor.
I use the following setting:
Res st Current | 1A |
Estimated Freq | 70Hz |
Motor Pole Pairs | 1 |
Motor max Current | 1.5A |
Motor Max freq | 120Hz |
I get these results
RS | 75 |
LS_D and LS_q | 157.35mH |
Flux | 3.5082767V/Hz |
The system works well and i can spin up to 2400 rpm.
With SVM Modulation set to 2.00
because i need 3000rpm i try switch to the recommended CCS LABs.
I entered my values in ccs
#define USER_MOTOR_TYPE MOTOR_Type_Pm #define USER_MOTOR_NUM_POLE_PAIRS (1) #define USER_MOTOR_Rr (NULL) #define USER_MOTOR_Rs (NULL) #define USER_MOTOR_Ls_d (NULL) #define USER_MOTOR_Ls_q (NULL) #define USER_MOTOR_RATED_FLUX (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 (1.5) #define USER_MOTOR_FLUX_EST_FREQ_Hz (70.0) #define USER_MOTOR_FREQ_LOW (10.0) // Hz - suggested to set to 10% of rated motor frequency #define USER_MOTOR_FREQ_HIGH (50.0) // Hz - suggested to set to 100% of rated motor frequency #define USER_MOTOR_FREQ_MAX (60.0) // Hz - suggested to set to 120% of rated motor frequency #define USER_MOTOR_VOLT_MIN (80.0) // Volt - suggested to set to ~20% of rated motor voltage #define USER_MOTOR_VOLT_MAX (240.0) // Volt - suggested to set to 100% of rated motor voltage
after i enable and run LAB2A.
The resistance was measured equaly.
The the motor don't start spinning.
I uncheck "run" and "System enable" in the GUI after some waiting time. But don't switch off the system. After further 2 Minutes Shunt R11 blows up, Mains fuse tripped and the 15V Power Supply are in current limiting.
After some time without power the overcurrent on 15V is gone.
My questions:
- What might be properly damaged? R11 ! U1 ??? Are there some other critical parts?
- How i can get LAB2a to work?
- Why works the instaSpin FOC GUI so well and the LABs are a completly documentation and functional nightmare?
Thanks for all possible help and support.
