universal_motorcontrol_lab_f280013x
Hello, I am using the main chip f2800137, and there is no mention in the general routine documentation about whether the resistance and inductance in the motor parameters distinguish between Y-type and delta-type configurations. However, after looking up the motor parameters for BLY172s in the routine, I found that this motor is of delta-type configuration, but the written motor parameters are the official line-to-line resistance and half of the inductance. This is different from the program for f28027. When I previously used the 027, the measured motor line-to-line resistance and inductance divided by 3 were written in, and it worked normally with load. However, dividing by 2 did not work. 1. Could you please confirm how to write the parameters for the delta-type motor of 137, so that it is consistent with the 027? 2. Secondly, why is there such a large error in the identification of the motor parameters for 137, sometimes 5uh and sometimes 1uh? Should I increase the chopping frequency
