Re: Motor Testing
I would strongly encourage teams to try testing their motors. This isn't necessarily a practical thing to do and I wouldn't expect that you'll be able to pick-and-choose motors from a sample set. HOWEVER, this can be a highly effective educational tool.
I've attached a motor model with "everything you need to know". With a little bit of differential equations and math, a nice simulation can be created using only a handful of parameters. It's interesting to note that their are really only 4 parameters of interest when specifying a motor (other than size and maximum power/current/voltage) - winding resistance, winding inductance, "motor constant" and motor rotor inertia.
Enjoy!
