Hello all. I'm looking to find companies in the United States that
perform testing and evaluation on small brush-less DC motors. I'm
talking about generating torque/speed curve profiles, dynamometer
testing, winding resistance and inductance measurement, etc., not just
"yeah Wally, it spins real purdy!" kind of testing.

Sounds like a real specialty shop.

Is this for some sort of QA function? Or are you trying to find the
motor parameters as the basis for some design/analysis work? If its the
latter, can you get the data from the manufacturer? If not, your best
bet might be to look for a cal-cert lab that deals with
electromechanical transducers.
