Hi everybody,
Today I started connecting my MXUS 3K v3 (3T) to my Sabvoton SVMC72150.
Swapped green and yellow phase and Hall cables and set Pn to 23. Hall angle test worked fine.
I plan to run it at 20 or 21S, but for the moment I am testing with a 48V (13S) battery.
For the moment there are two issues:
1) I have a Sabvoton with a white cable for the temp sensor which I have connected to the white temp sensor cable of the MXUS. It should be a KTY83/110 sensor.
The problem is that the value for motor temperature is always around -35 to -40 degrees.
2) At 54V battery voltage and without flux weakening, the highest no-load rpm I have seen in the Sabvoton app was 588 which is a bit low I think. kv is 11.9 for my 3T, so it should be aroud 640 at 54V which I can only achieve with some flux weakining. Do you think this is normal or could there be a problem?
