Unfortunately, I do not have much info as to what causes this. I am using the FOC library with a 3-phase BLDC and encoder as speed feedback. Sometimes when I send a ramp command, the motor flies to ~5000 RPM regardless of the target speed I set. It i...

My datasheet (STM32F103VC) states the Vbat current draw is 1.4uA. Is there a way to reduce this? I only need the backup domain for RTC/LSE. I know there are many backup registers as well. Could I turn these off to reduce current draw?

Hi,I have been struggling to run my motor at low speeds and I suspect the Hall Sensors are the limiting factor. In UM1052 I found the following line on page 36. "For speed regulation, there is absolutely no need to have a sampling time lower than the...
