Question: If we run the FP motor at 30% power and stall it for no more than 10 seconds, will this still cause thermal trip/magic smoke or is this a "safe" option?
The FPs have an external fan attached to their output shaft to keep them cool. Stalling the FP not only causes high current, but also stops this cooling fan. Not a good idea.

I would not suggest running an FP in stall for very long at all (not even 10 seconds).

Just my opinion.
