Hi,

Currently I am working on two wheeler project with QS motor 2kW, for development purpose I use STEVAL-CTM009 and Nucleo-F103RB. I use lab bench supply (30V,3A) as VBUS.

I tried to driving the BLDC with sensorless algorithm but after few seconds the fault occur (start-up fail or speed fedback)

Really appreciate any help and advice.
