Great video! For the problem you're describing at 1:04, I've always wondered to what point I need to worry about drawing too much current... like due to inrush current of motors starting up... For instance, in RC Cars, they don't have any inrush current protection or monitoring, right? Is that because those use cases are safe enough, or because they're basically toys and they don't care?
Hi Jeffrey, thanks for your question. Unfortunately, there is no standard for “Motor current rating”. Electric motors are great because they can momentarily provide much more power than their steady state rating. The main limitation is thermal. If you send too much current for too long to the motor, the windings will melt or burn. The thrust stand is a great way to test what are the limits of your motor in a control environment if you are willing to burn a few in the process. That sounds like a good idea for a future video :)
