Setting the FOC Ts to 45us (instead of 37.5us , ndr) makes the motor spin with more oscillations, is this expected?

This is a test with 45us , and the AMC_BLDC architectural model.

Note that with 65mA of target we get close to the no-load current.

45us

Now with the 37.5us :

37_5us

At a first glance, the behaviour is very much comparable between the two.

There's only an issue with -65mA, but it's probably due to a missing significant resistant load.

I think that we can reasonably consider the two outcomes very similar 👍🏻
Thanks for the test, @mfussi66!
