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.

It is for QA. *Essentially we have an old motor vendor we're not too

Couldn't you make up a dummy load of a generator connected to the
output shaft of the motor, and then using a strobe and ammeter measure
the current draw for various loads / speeds and do that for both
motors to see if they draw comparable current for the same load and
speed?
