Hello,
I am working with a BLDC motor in sensorless mode using ST Motor Control Workbench and Motor Pilot.
When I press the Start button in Motor Pilot, the motor status changes to Running based on the target speed I set, but the motor shaft/wings do not actually rotate.
Additional observations:
The motor is not in a locked condition (not drawing stall current).
If I try to manually rotate the motor during startup, it still does not continue spinning.
On Motor Pilot, the motor state shows Running, but physically it is stationary.
My Questions:
Why does the motor state show Running while the rotor is not moving?
How can I debug this issue further to ensure proper startup in sensorless mode?
Any guidance or suggestions will be greatly appreciated.
Thank you
Best Regards
Rahul
