The measurement is taking too time

[M N]

I have "Nucleo F303-RE" and "STEVAL-IPM15B" .( and some custom PCB which are not important in this question)

So I have connected 2 board together and test two BLDC motor . And run first bldc and everything works good and get me detail about motor ( Rs , LS , Ke and ...) But when I connect next motor to get detail It gives me error which shows in below picture :

*** Also speed feedback little circle will red sometimes . ***

so after this I have changed RPM to more high and more low and some random value . But none of them work .

So I think our second motor is not bldc or is some especial type of bldc I will add the picture of inside of motor maybe help to more answer :

 

So as It shows it seems to be not synchronous motor but sure bldc . so why st motor profiler can't specify motor paramater ?

I read a lot of post related to this kind of error in st community and it seems no one will help about this ! It's not good .
