Hi,
I have some questions about the motor parameter setting in the USER MOTOR and ID Settings.
1.The USER_MOTOR_RS indicates the identified phase to neutral resistance in a Y equivalent circuit。For three-phase winding , I can measure every two-phase resistance， and calculate the average。 Should the delta connection be equivalent to Y connection,and then calculate the resistance?
2.The USER_MOTOR_LS_q(or USER_MOTOR_LS_d) indicates identified average stator inductance. I just have a handheld LCR Meter, and just can measure every two-phase resistance ,and average them.Is this method right to calculate the USER_MOTOR_LS_q?
3. Dose the stator inductance of the motor very with the ambient conditions such as the temperature of motor winding , the rotating speed or the instant angle ? The INSTASPIN-FOC offers the Rs online Rcalibration, and I find that the Rs and the Flux will very when I run the function of runRsOnline except the Lsd_H and Lsq_H. The Lsd_H and Lsq_H are showing no deference with the value of USER_MOTOR_LS_q. Dose that mean the Lsd_H and Lsq_H won't very with the temperature or other ambient conditions.
